Two carts are initially moving to the right on a low-friction track, with cart 1 behind cart 2. Cart 1 has a speed twice that of cart 2 and so moves up and rear-ends cart 2, which has twice the inertia of cart 1. A. Suppose that the the initial speed of cart 2 is v. What is the speed of cart 1 right after the collision if the collision is elastic? Express your answer in terms of v. B.What is the speed of cart 2 right after the collision if the collision is elastic? Express your answer in terms of v.

A 75.0 kg ice skater moving at 8.50 m/s crashes into a stationary skater of equal mass. After the collision, the two skaters move as a unit at 4.25 m/s. If the impact time is 0.140 s, what are the magnitudes of the average forces experienced by each skater during the collision? Force experienced by moving skater Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N Force experienced by stationary skater Suppose the average force a skater can experience without breaking a bone is 4500 N. Does a bone break? Yes No

6.3 PQ1 Newton's second law can be stated that the force is equal to the rate of change of momentum, F = d(mv)/dt. Tak- ing the derivative by parts yields F = m(dv) / (dt) + v(dm) / (dt). This does not correspond to F = ma. What is the source of the discrepancy? %3D
