A girl throws a ball at a vertical wall 4 m away as shown in Figure. The ball is 2 m above ground when it leaves the girl's hand with an initial velocity of ??⃗0 = (10 ??/??)(??̂+ ??̂) or 10√2 ??/?? at 45º. When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains unchanged. Where does the ball hit the ground?
