Safety engineers estimate that an elevator can hold 20 persons of 75kg average mass. The elevator itself has a mass of 500kg. Tensile strength test how the cable supporting the elevator can tolerate a maximum force of 2.96X10^4N. What is the greatest acceleration that the elevators motor can produce without breaking the cable? (show work)

Answers

The greatest acceleration that the elevators motor can produce without breaking the cable is 5 m/s².

The given parameters;

average mass of the 20 persons = 75 kgmass of the elevator, m = 500 kgtensile strength of the elevator, T = 2.96 x 10⁴ N

The total mass the elevator can support;

M = 500 kg + 20(75 kg)

M = 2000 kg

The greatest acceleration that the elevators motor can produce without breaking the cable occurs when the elevator is moving upwards;

T = M(a + g)

[tex]2.96 \times 10^4 = 2000 (a + 9.8)\\\\2.96 \times 10^4 = 2000a + 19600\\\\29600 - 19600 = 2000a\\\\10,000 = 2000a\\\\a = \frac{10,000}{2000} \\\\a = 5 \ m/s^2[/tex]

Thus, the greatest acceleration that the elevators motor can produce without breaking the cable is 5 m/s².

Hi there!

Average speed = Distance / time

From the previous question, distance = 17m, so:

Speed = 17/12 ≈ 1.417 m/s

Average velocity = DISPLACEMENT/ time

Displacement = 1m, so:

Plzzz help me

Answers

Answer:

1.647376

Explanation:

Change the divisor 12.96 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

2135 ÷ 1296 = 1.647376

and therefore:

21.35 ÷ 12.96 = 1.647376

Both calculated to 6 decimal places.

Answers

Hi there!

On a horizontal circular track with friction, the net force acting in the horizontal direction is:

∑F = Fκ, or the force of kinetic friction.

We know that ΣF = Mv²/r, so:

Mv²/r = Fκ

Plug in the given values to solve:

(1750)(35²)/80 = Fκ

Thus:

Fκ = 26796.875 N

At the end of the Giant Drop free fall ride, riders experience a large experience a large upward normal force to bring their falling bodies to a stop. Determine the normal force value required to accelerate a 52.1-kg physics student with an upward acceleration of 27.4 m/s/s.

Answers

Newton's second law allows us to find the force applied to the student so that it has an upward acceleration of 27.4 m / s² is:

            F = 1.94 10³ N

Newton's second law says that the force is proportional to the product of the mass and the acceleration of the body.

         ∑ F = m a

Where F is the force, m the mass and the acceleration of the body.

A free body diagram is a diagram of the forces without the details of the bodies, in the attachment we have a free body diagram of the system.

They indicate that the student's mass is 52.1 kg and his acceleration is 27.4 m / s², let's write Newton's second law.

           F - W = ma

            F = m a + W

Body weight is.

            W = mg

            F = m (a + g)

We calculate.

            F = 52.1 (27.4+ 9.8)

            F = 1.94 10³ N

In conclusion using Newton's second law we can find the force applied to the student is:

            F = 1.94 10³ N

Investigators studying the effect of hitting a soccer ball with the head are using a force plate to look at the forces in ball collisions; the force when the ball hits a player's head will be similar. A 0.43 kg ball is launched at a force plate at 16 m/s. Smoothed data for the force versus time for the collision are shown in (Figure 1).

Answers

The integral of the function of the force applied to the time of application

of the force gives the impulse of the force.

The speed with which the ball rebounds from the plate is approximately

34.23 m/s.

Reasons:

Force = Rate of change of momentum

F × t = m·(v₂ - v₁)

Where;

Speed of the ball, v₁ = 16 m/s

v₂ = The speed with which the ball rebounds from the plate

The impulse, I, of the force is given by the area under the curve.

The height of the triangular curve, h = 2,500 N

The base length of the triangular curve = 7 ms.

Area of a triangle = [tex]\frac{1}{2}[/tex] × Base length × Height

Therefore, we have;

[tex]Area \ under \ the \ curve, \, I = \dfrac{0.007 \times 2500}{2} = 8.75[/tex]

8.75 = 0.48 × (v₂ - 16)

v₂ ≈ 34.23 m/s

Therefore, the speed with which the ball rebounds, v₂ ≈ 34.23 m/s.

A non-uniform rod XY of mass 40 kg and length 5.0 m lies on the horizontal ground. Its centre of gravity is 2.0 m from the end X. Calculate the vertical force P, that will just be sufficient to lift the end Y from the ground. Why would the force P, if applied at the end X not be sufficient to lift the end X from the ground? (8 = 10.0 (SC/GCE) ms-2)​

Answers

The vertical force P, that will just be sufficient to lift the end Y from the ground is 600 N.

If the force P is applied at end X, it will not be sufficient to lift end X from the ground because the force P is acting downwards.

The sketch of the rod is presented as follows;

|---- 2 ----------|---------------------- 3 ----------------------|

X-----------------------------------------------------------------Y

P                    ↓

                      40 kg

Take moment about the center of gravity;

P(2) = 40 x g (3)

2P = 40 x 10 (3)

2P = 1200

P = 600 N

Thus, the vertical force P, that will just be sufficient to lift the end Y from the ground is 600 N.

If the force P is applied at end X, it will not be sufficient to lift end X from the ground because the force P is acting downwards.

Answer:4.99km

Explanation:

s = (1/2)at²

t = 0.5 minute*(60sec/1min)=30 sec

s = (1/2)*(2.2m/s²)(30sec)²

s = 990m

Reference point is 4km at start.  Distance from reference point is 9km + 0.990km = 4.99km

between a smooth and a rough surface, which of the two surfaces is easier to slide and why?​

Answers

Answer:

When two surfaces slide against each other, a force called friction makes them stick very slightly together. Smooth surfaces, like ice and glass, are easy to slide over

Explanation:

They create very little friction. Rough surfaces like rock and sand create much more friction, and are easy to grip on to.

Hello There!

Smooth Surfaces are easier to slide over. That's true.

Take an object and slide it across a rough surface. Now, slide the same object across a smooth surface.

What do you see?

I expect you wil find out that smooth surfaces are easier to slide over.

Reason:

Smooth surfaces have less friction than rough ones.
