Problem: A ball of mass 10 g and with a velocity 50 m/s is moving in the x direction hits a stationary (at rest) wooden block of mass 5.0 kg. The wooden block is sitting on a frictionless horizontal surface. The ball hits the block and gets embedded in it and then the block-bullet combination moves. The ball and wood combination moves above the horizontal surface.
(a) What is the speed of the ball and block right after collision?
(b) What is height h, if the ball and block combination barely make it to the top? All surfaces are frictionless.
