I have this homework problem that I keep going in circles with! Any hints? A .500kg ball is dropped from rest at a point 1.20 m above the floor. The ball rebounds straight upward to a height of .700 m. What are the magnitude and direction of the impulse of the net force applied to the ball during the collision with the floor. Ok so I know that Vo= 0m/s and I need to find the final velocity and time right? Do I need to break apart into x and y components?
