A woman throws a ball at a vertical wall d = 4.6 m away. The ball is h = 2.3 m above ground when it leaves the woman's hand with an initial velocity of 19 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?

(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?
