A UPS worker places a 5.00 kg package at the top of a smooth ramp 2.60 m above the horizontal and gives the package an initial velocity of 4.25 m/s as it slides down the ramp. After it reaches to the bottom of the packaging ramp, the box slides across a smooth floor until it compresses a spring with a stiffness of 3830 N/m.

a) How much will the spring be compressed before the block comes to a stop?

b) If the spring can do work at a rate of 385 W, how long will it take for the spring to be compressed by the package?

Expert Solution

The spring will compressed by 0.192 m = 19.2 cm

It will take 0.366 second or 366 milliseconds

A 20.0 kg package is positioned at the bottom of an inclined ramp. The ramp has a length of 15.0 m, and an inclination angle of 34.0°above the horizontal floor. A constant force having a magnitude 290 N, and directed parallel to the horizontal floor, is applied to the package in order to push it up the ramp. While the package is moving, the ramp exerts a constant frictional force of 65.0 N on it. a. Draw a free-body diagram...

A 35.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.500 and the constant of the spring is k = 6000 N/m. What is the net impulse exerted on...

A 25.0-kg crate is initially at rest at the top of a ramp that is inclined at an angle θ = 30.0 ◦ above the horizontal. You release the crate and it slides 1.25 m down the ramp before it hits a spring attached to the bottom of the ramp. The coefficient of kinetic friction between the crate and the ramp is 0.400 and the constant of the spring is k = 5000 N/m. How far does the crate compress...

A toy car with a mass of 1 kg starts from rest at the top of a ramp at point A.

A toy car with a mass of 1 kg starts from rest at the top of a ramp at point A. The toy car is released from rest, rolls 2.0 meters down the ramp, then another 3.0 meters across the floor to point B where its speed is measured to be 4.24 m/s. The air exerts a resistance force of 2.0 N on the car as it moves from A to B. Find the initial height of the car at...
