Question

A mass (MA=3kg) slides down a frictionless ramp of height
H=12m and collides with a second mass (MB=5kg), moving towards mass A at
vB=8m/s . Assume the collision occurs with both masses moving horizontally.

a) (5 pts) What is the velocity of Mass A at the bottom of the ramp?
va =____________

b) (10pts) Assuming the collision is elastic, what are the velocities of the two
masses after the collision?
A v'a =____________
B v'b =____________

c) (10pts) How far back up the ramp does Mass A travel?
Hnew=___________
