A box with mass m sits at the bottom of a long ramp thatis sloped upward at an angle a above the horizontal. You give the boxa quick shove, and after it leaves your hands it is moving up the rampwith an initial speed v0. The box travels a distance d up the ramp andthen slides back down. When it returns to its starting point, the speedof the box is half the speed it started with; it has speed v0 /2. What isthe coefficient of kinetic friction between the box and the ramp? (Youranswer should depend on only a.)

The human head can be considered as a3.3-kg cranium protecting a 1.5-kg brain, with a small amount ofcerebrospinal fluid that allows the brain to move a little bit insidethe cranium. Suppose a cranium at rest is subjected to a force of2800 N for 6.5 ms in the forward direction. (a) What is the finalspeed of the cranium? (b) The back of the cranium then collideswith the back of the brain, which is still at rest, and the two movetogether. What is their final speed? (c) The cranium now hits anexternal object and suddenly comes to rest, but the brain continues to move forward. If the front of the brain interacts with thefront of the cranium over a period of 15 ms before coming to rest,what average force is exerted on the brain by the cranium?

Two boxes are at rest on a smooth, horizontal surface. The boxesare in contact with one another. If box 1 is pushed with a forceof magnitude F = 12.00 N, the contact force between the boxesis 8.50 N; if, instead, box 2 is pushed with the force F, the contactforce is 12.00 N - 8.50 N = 3.50 N. In either case, the boxes movetogether with an acceleration of 1.70 m>s2. What is the mass of(a) box 1 and (b) box 2?
