Compute all parts of given problem:
Problem: A 54.1-kg person, running horizontally with a velocity of +3.45 m/s, jumps onto a 17.5-kg sled that is initially at rest.
Part A: Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away.
Part B: The sled and person coast 30.0 m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow?
I need help to find the velocity of the sled and person as they move away.
