A 79.5kg person, running horizontally with a velocity of +2.34m/s,jumps onto a 11.8kg 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. b) The sled and person coast 30.0m on level snow before coming to rest. What is the coefficient of kinetic friction between the sled and the snow? Note: the tolerance is positive negative 1 in the 3rd significant digit (a) Number i (b) Number i Units Units
