A woman throws a ball at a vertical wall d = 3.0 m away. The ball is h = 1.5 m above ground when it leaves the woman's hand with an initial velocity of 12 m/s at 45°. When the ball hits the wall, the horizontal component of its velocity is reversed; the vertical component remains unchanged. (Ignore any effects due to air resistance.)
(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 the wall? s
(c) Where did the ball hit the wall? m (above the ground)
(d) How long was the ball in the air after it left the wall? s
