Question: A girl throws a ball at a vertical wall 4 m away. The ball is 2 m above the ground when it leaves the girl's hand with an initial velocity v0= (10i+10j) m/s. When the ball hits the wall the horizontal component of its velocity is reversed; the vertical component remains unchanged.
Part A: Where does the ball hit the ground?
I need the right answer and steps of solve this question. Thanks!
