A 60.5-kg person, running horizontally with a velocity of +3.76 m/s, jumps onto a 10.4-kg sled that is initially at rest.
(a) Ignoring the effects of friction during the collision, find the velocity of the sled and person as they move away.
m/s
(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?

    This one I'll help you with
    a)60.5+10.4=70.9
    70.9/3.76=18.856382
    b)18.856382/30.0=0.628546
