A woman throws a ball at a vertical wall d = 4.6 m away. Theball is h = 2.3 m above ground when it leaves the woman's hand withan initial velocity of 19 m/s at 45°. When the ball hits the wall,the horizontal component of its velocity is reversed; the verticalcomponent remains unchanged. (Ignore any effects due to airresistance.)
(a) Where does the ball hit the ground? m(away from the wall)
(b) How long was the ball in the air before it hit thewall? s
(c) Where did the ball hit thewall? m (above theground)
(d) How long was the ball in the air after it left thewall? s
