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?

Solutions

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...
