Question: A 468 kg mass is sliding on a horizontal frictionless surface with a speed of 9.3 m/s when it collides with a 82 kg mass initially at rest. The masses stick together and slide up a frictionless track at 60 degrees from horisontal. The acceleration of gravity is 9.8 m/s^2.

1) What is the speed of the two blocks?

I figured out the speed of the two blocks: 7.91345 m/s

2) To what maximum height h above the horizontal surface with the masses slide? Answer in units of m.
