Question

A.) Your mass is 75.2 kg, and the sled s mass is 18.3 kg. The sled is moving by itself on the ice at 4.15 m/s. You parachute vertically down onto the sled, and land gently. What is the sled s velocity with you now on it?

B.) A block of mass 1.12 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 4.23 m/s. It eventually collides with a second, stationary block, of mass 3.60 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.12-kg and 3.60-kg blocks, respectively, after this collision?
