A rubber ball with a mass of 210 grams is thrown exactly horizontally from a height of 2 meters with an initial speed of 13 m/s. When it strikes the ground, it bounces off at the same angle it made when it landed. During the bounce, it loses 20% of it's kinetic energy to dissipative forces. How high does it go after bouncing?
I have this figured out but not sure if it is correct...if anyone can tell me how they would do it I would greatly appreciate it..thanks
