5 A 75kg person jumps horizontally out of a tree with an initial velocity of 3m/s i. The person lands in a 12kg wagon. The wagon is initially at rest, and located 2.0m below the tree branch. a. Calculate the vertical speed of the person just before they hit the wagon. b. Calculate the velocity of the person just before they hit the wagon. c. Calculate the momentum of the person just before they hit the wagon. d. Calculate the momentum of the wagon and person after the person lands.
