In this example we will add friction to an inclined ramp. Of course, friction does work and we will need to determine its contribution to WotherWother. A crate full of machine parts sits on the floor; the total mass is 8.0 kg. The crate must be raised to the floor of a truck by sliding it up a ramp 2.5 m long, inclined at 30∘. The shop foreman, giving no thought to the force of friction, calculates that he can get the crate up the ramp by giving it an initial speed of 5.0 m/S at the bottom and letting it go. Unfortunately, friction is not negligible; the crate slides 1.6 mm up the ramp, stops, and slides back down. (Figure 1) shows the situation. (a) Assuming that the friction force acting on the crate is constant, find its magnitude. (b) How fast is the crate moving when it reaches the bottom of the ramp? PART B Suppose the foreman had released the box from rest at a height of 0.25 m above the ground. What would the crate's speed be when it reaches the bottom of the ramp?
