A 200 g steel ball hangs on a 0.75 m long string. The ball ispulled sideways so that the string is a 60 degree angle, thenreleased. At the veery bottom of its swing the ball strikes a 1 kgsteel block that is resting an a frictionless table. Assuming thecollision to be perfectly elastic. a).- Determine the speed of the ball after the collision. b).- To what angle does the ball rebound? c).- What quantities are conserved in the collision?
