Beasy is driving in his car to take care of some errands. The first errand has him
driving to a coffee shop 2 km East and 6 km North of his starting location. Once he
completes that errand, he drives to a thrift store which is 4 km East of the first errand.
What is the displacement of the car from the starting point, rounded to the nearest
km?

Answers

Answer 1

At this point in the story, Beasy has driven his car (2+6+4) = 12 km.

He is parked at the thrift store, (2+4) = 6 km East and 6 km North of his starting point.

As the crow flies, the thrift store is √(6km² + 6km²) in a straight line from the starting point.

That's √(72 km²) , which works out to 8.485 km .  When rounded to the nearest whole km, he can phone up his wife and tell her he's "eight kilometers from home can you hear me now ?".

Displacement is a vector, so to answer the question completely, we also need to state its direction.

The angle from home to the thrift store, relative to East, is arctan(6km/6km).

That's 45 degrees.  

The full displacement vector is 8.485 km Northeast.

Answer 2

From the question, Beasy drives 2km East and 6 km North. He then drives 4 km East of the first errand. An illustrative diagram is shown in the attachment below.

From the diagram S is the starting starting point, C is coffee shop and T is the thrift store.

The displacement of the car from the starting point is giving by /TS/ in the diagram. To calculate /TS/, consider the right-angled triangle TSQ, /TS/ is the hypotenuse.

From The Pythagorean theorem, in a right-angled triangle, the square of the longest side (hypotenuse) equals sum of the squares of the other two sides.

That is,

/TS/² = /SQ/² + /TQ/²

But /TQ/ = /CP/ = 6km

and /SQ/ = /SP/ + /PQ/

/SP/ = 2 km, /PQ/ = 4 km

∴ /SQ/ = 2 km + 4 km

/SQ/ = 6 km

Hence,

/TS/² = 6² + 6²

/TS/² = 36 + 36

/TS/² = 72

/TS/ = [tex]\sqrt{72}[/tex]

/TS/ = 8.485 km

/TS/ ≅ 8 km ( to the nearest km)

Hence, the displacement of the car from the starting point rounded to the nearest km is 8 km.

Lee is traveling in a train moving at a constant velocity of 35 m/s to the east. If Lee is seated on the train and staring at the seat directly in front of him, how fast does the seat in front of Lee appear to be moving relative to Lee?

Answers

Answer:

0 m/s or stationary

The seat in front of Lee appear to be at rest

Explanation:

When the motion of a person or object is found by comparing the person or objects motion with regards to a stationary object or an object in motion, the result is the relative motion of the person or object to the stationary or moving object

In the question, Lee is comparing the motion of the chair in front of him with regards to the motion of the chair he his sitting on.

The speed of both chairs are the same as the speed of the train in which they are attached.

Therefore, as the seats are fixed relative to each other such that there is no change in their relative position and therefore, no or 0 m/s relative velocity with each other.

A person holding a lunch bag is moving upward in a hot air balloon at a constant speed of 7.7 m/s . When the balloon is 21 m above the ground, she accidentally releases the bag. Part A What is the speed of the bag just before it reaches the ground

Answers

Answer:

The speed of the bag just before it reaches the ground is 21.71 m/s.

Explanation:

The speed of the bag can be found using the following equation:

[tex] v_{f}^{2} = v_{0}^{2} - 2gy [/tex]

Where:

[tex]v_{f}[/tex] is the final speed =?

[tex]v_{0}[/tex] is the initial speed = 7.7 m/s

g: is the gravity = 9.81 m/s²

y: is the height = 21 m

[tex]v_{f}^{2} = v_{0}^{2} - 2gy = (7.7 m/s)^{2} - 2*9.81 m/s^{2}*(-21 m) = 471.31 m^{2}/s^{2}[/tex]

[tex]v_{f} = 21.71 m/s[/tex]

Therefore, the speed of the bag just before it reaches the ground is 21.71 m/s.

An object with a density of 0.85 g/cc is dropped into each of the two beakers shown below. Beaker 1 has a density of 0.5 g/cc. Beaker 2 has a density of 1 g/cc. What will happen to the object in each case?

Answers

Answer:

The object will sink in the liquid in beaker 1.

The object will float in the liquid in beaker 2

Explanation:

The density of an object relative to the density of a fluid determines if the object floats or sink in a fluid. The density of a material is the measure of the amount of mass of that material packed into a unit volume of that material.

For the beaker 1, the liquid in this beaker has a density of 0.5 g/cc, which is lesser than the density of the object (0.85 g/cc). This means that the object will add more mass than there should be to the volume of the space it displaces within the field. This results in the object sinking in the fluid.

For beaker 2, the liquid in this beaker has a density of 1 g/cc, which is more than the density of the object (0.85 g/cc). This means that the object will add less mass than there should be to the volume of the space it displaces within the field. This results in the object floating in the fluid.

A hummingbird beats it’s wings up and down 60 times a second what is the frequency and period

Answers

Answer:

Period = 0.0167 seconds

Frequency = 60 Hz

Explanation:

Period: This can be defined as the time take by a wave to complete on cycle. The S.I unit is (s)

Frequency: This is the number of cycle completed by a wave. The S.I unit is (Hz)

From the question,

T = t/n................................... Equation 1

Where T = period, t = time take to complete n oscillation, n = number of oscillation.

Given: t = 1 seconds, n = 60.

Substitute these values into equation 1

T = 1/60

T = 0.0167 seconds.

Also,

F = 1/T........................... Equation 2

Where F = frequency

Given: T = 0.0167 seconds,

Substitute these value into equation 2

F = 1/0.0167

F = 60 Hz

From what I see, it's saying that every minute, the ant can move 30 meters.  So how many meter would it move in 45 minutes?

30 meters = 1 min

1 min x 45 = 45 min

30 meters x 45 = 1,350 meters

A small metal sphere has a mass of 0.19 gg and a charge of -23.0 nCnC. It is 10.0 cmcm directly above an identical sphere that has the same charge. This lower sphere is fixed and cannot move. If the upper sphere is released, it will begin to fall.What is the magnitude of its initial acceleration?

Answers

Answer:

  a = -7.29 m / s²

Explanation:

For this exercise we must use Newton's second law,

          F -W = m a

Force is electrical force

         F = k q₁ q₂ / r²

         k q₁ q₂ / r² -mg = m a

indicate that the charge of the two spheres is equal

         q₁ = q₂ = q

         a = (k q² / r² - m g) / m

         a = k q² / m r² - g

Let's reduce the magnitudes to the SI system

        m = 0.19 g (1kg / 1000 g) = 1.9 10⁻⁴ kg

        q1 = q2 = q = -23.0 nC (1C / 10⁹ nC) = -23.0 10⁻⁹ C

        r = 10.0 cm (1m / 100cm) = 0.1000 m

let's calculate

        a = 9 10⁹ (23.0 10⁻⁹)² / (0.1000² 1.9 10⁻⁴) - 9.8

        a = -7.29 m / s²

The negative sign indicates that the direction of this acceleration is downward

A boat that moves with a constant velocity of 12 m/s is moving on a river with a
constant current of 4 m/s. What is the resultant velocity of the boat if:
a) The boat is traveling to the north and the current is to the south?
b) The boat is traveling to the south and the current is to the south?
c) The boat travels to the east, across the current, while the current is to the south.

Answers

Explanation:

Given that,

Velocity of boat, [tex]v_b=12\ m/s[/tex]

Velocity of current, [tex]v_c=4\ m/s[/tex]

(a) If the boat is traveling to the north and the current is to the south,

[tex]v_b=12j\ m/s[/tex]

[tex]v_c=-4j\ m/s[/tex]

The resultant velocity,

[tex]v_r=12-(4)=8\ m/s[/tex] due North

(b) If boat is traveling to the south and the current is to the south,

[tex]v_b=-12j\ m/s[/tex]

[tex]v_c=-4j\ m/s[/tex]

Resultant velocity,

[tex]v_r=12+4=16\ m/s[/tex] due south

(c) If the boat travels to the east, across the current, while the current is to the south.

So,

[tex]v_r=\sqrt{12^2+4^2}\\ \\v_r=12.64\ m/s[/tex]

A football coach walks 18 meters westward, then 12 meters
eastward, then 28 meters westward, and finally 14 meters
eastward.

Answers

Answer:

Displacement = 20

Direction = westward

Explanation:

Given that a football coach walks 18 meters westward, then 12 meterseastward, then 28 meters westward, and finally 14 meters

eastward.

To calculate the displacement,

Let eastward = negative

Westward = positive

Displacement = 18 - 12 + 28 - 14

Displacement = 46 - 26

displacement = 20 metre

Since the answer is positive, the direction is westward.
