Problem 4 10 marks Two solid spheres of total masses m, and m,2 respectively collide such that at the instant of impact the x axis passes through the centers C1 and C2 of the spheres. The collision is perfectly elastic (that is, (vi - v2) =-(v^-v2) î). Find their velocities after impact (vi and v) in terms of their velocities before impact (vi and v2 or vi, V2,1 and 02). j C2 2/ 01

Chapter 2, Problem 2/084 Multistep A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 39 km/h at the 68-m mark. He then maintains this speed for the next 66 meters before uniformly slowing to a final speed of 34 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Finish line 39.9 m ▼Part 1 Your...
