Two blocks of mass 1 kg sit on a level track and feel a kinetic friction coefficient of μk = 0.15. The first block is sliding along a track with an initial velocity of 3 m/s and the other block is stationary. After sliding for 1m, the first block collides with the second block in a perfectly inelastic collision. After the collision, the stuck-together blocks slide to a stop.
a. What is the speed of the first block just before the collision?
b. What is the speed of the blocks just after the collision?
c. What is the sliding distance for the stuck together blocks?
