A woman throws a ball at a vertical wall 4.0 m away (Figure 3-40). The ball is 2.0 m above ground when it leaves the womans hand with an initial velocity of 14 m/s at 45, as shown. When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains uncha
