Answer:

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

Explanation:

Answer:

0kgm/s

Explanation:

The momentum of the empty car is zero.

Momentum is the quantity of motion a body possess. The more the mass and velocity by which a body moves, the higher is its momentum.

 Momentum  = mass x velocity

Since the second car is at rest, the velocity is 0m/s;

 So;

     Momentum  = 100 x 0 = 0kgm/s

Therefore, a body at rest has zero momentum

If it is 9 am in San Francisco, then there will be 12pm in New York. it happens because of spin rotation of our earth.

A clock or a timepiece is a device used to measure time. The clock is one of the oldest human inventions. It has three hands moves in the circle. one is second hand, which show seconds. Second hand shows hours and third hand which is smaller than other shows hours.

San Francisco, California is 3 hours behind New York. There will be 12pm in New York when it is 9 am in San Francisco. Day and night happens because of our earth is spinning about itself.  when we take a football in the dark room and illuminated it by the torch, then one side of the ball gets illuminated and other side of the ball gets dark due to shadow of its own, Same happens with our earth. it this case torch is our sun and earth is our football.  The people who are on the darker side they are in the night and who are in the light side they are in the morning.

Morning starts where edge of the light is. Tme changes with lateral distance on the earth. The points which is on same longitude have same time. There is lateral displacement from San Francisco to New York. Therefore there is time lag between them.

Hence there is time lag.

Explanation:yes

An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.

Answer:

The electric field will exert a force that accelerates the charged particle. The electric field has a direction, positive to negative. ... If it is moving in the opposite direction it will decelerate. If a negative charge is moving in the same direction as the electric field vector the particle will decelerate.

Answer:

2500miles

Explanation:

Given parameters:

Time of travel  = 5hrs

Average speed  = 500miles/hr

Unknown:

Distance between the two cities  = ?

Solution:

To solve this problem, we must understand that speed is the distance covered with time.

  So;

      Distance  = speed x time

Distance  = 500 x 5 = 2500miles

ALL of the meridians of longitude converge (come together) at the North and South poles.  So at a pole, the distance between different longitudes is ZERO.

if you're standing at the North or South pole, you're located at EVERY longitude, because any other longitude is zero distance from you.

You're also located at NO longitude.  Because . . .

==> If you're standing at the North pole and you take one step, it doesn't matter what direction you stepped, you've moved South. All directions from the North pole are South.

==> If you're standing at the South pole and you take one step, it doesn't matter what direction you stepped, you've moved North.  All directions from the South pole are North.

Answer:

75 kg.

Explanation:

From the question given above, the following data were obtained:

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

Kinetic energy (KE), mass (m) and velocity (v) of an object are related according to the following equation:

KE = ½mv²

With the above formula, we can obtain the mass of the object as illustrated below:

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

KE = ½mv²

937.5 = ½ × m × 5²

937.5 = ½ × m × 25

937.5 = m × 12.5

Divide both side by 12.5

m = 937.5 / 12.5

m = 75 Kg

Therefore, the mass of the object is 75 Kg.

Unknown:

Gravitational potential energy  = ?

Solution:

The gravitational potential energy of a body is the energy due to the position of the body.

It is expressed as:

     G.P.E  = mgh

m is the mass

g is the acceleration due to gravity

h is the height = 45 + 10  = 55m

G.P.E  = 60 x 9.8 x 55  = 32340J

Answer:

m = 74.44 kg

Explanation:

p = m × v

670 = m × 9

9m = 670

m = 670/9

m = 74.44 kg

Momentum of an body is defined as the product of mass and velocity.It s unit is kgm/sec.The value of mass will be 74.44 kg.

The measurement of mass in motion is called momentum. Momentum is equal to its mass multiplied by its velocity. Mathematically it is given as;

Momentum = Mass x Velocity

The given data in the problem will be

p is the momentum of runner=670 kgm/sec.

v is the velocity =9m/sec.

m is the mass =?

[tex]\rm p =mv\\\\\rm m =\frac{p}{v} \\\\\rm m =\frac{670}{9} \\\\\rm m =74.44 kg[/tex]

Hence the value of mass will be 74.44 kg.

Answer:

600m/s²

Explanation:

Given parameters:

Mass of car  = 600kg

Impulse  = 18000kgm/s

Time  = 0.05s

Unknown:

Acceleration  = ?

Solution:

To solve this problem, let us find the force that cause the impact first;

          Impulse  = Force x time

          Force  = [tex]\frac{impulse}{time}[/tex]    = [tex]\frac{18000}{0.05}[/tex]    = 360000N

So;

        Force   = mass x acceleration

         Acceleration  = [tex]\frac{Force }{mass}[/tex]    = [tex]\frac{360000}{600}[/tex]    

         Acceleration  = 600m/s²

Answer:

[tex]\boxed {\boxed {\sf a= -17.9 \ m/s^2}}[/tex]

Explanation:

Acceleration is equal to the change in velocity over the change in time.

[tex]a=\frac{v_f-v_i}{t}[/tex]

The initial velocity is 35.8 meters per second. The final velocity is 0 meters per second when the car comes to a complete stop. The time is 2.0 seconds.

[tex]v_f= 0 \ m/s \\v_i= 35.8 \ m/s \\t= 2 \ s[/tex]

Substitute the values into the formula.

[tex]a=\frac{0 \ m/s - 35.8 \ m/s }{2 \ s}[/tex]

Solve the numerator.

[tex]a= \frac{ -35.8 \ m/s} {2 \ s}[/tex]

Divide.

[tex]a= -17.9 \ m/s/s = -17.9 \ m/s^2[/tex]

The car's acceleration is -17.9 meters per square second. The acceleration is negative because the car was coming to a stop and slowing down.
