A woman throws a ball at a vertical wall d = 5.8 m away. The ball is h = 2.9 m above ground when it leaves the woman's hand with an initial velocity of 13 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.)
So much for the facts. What is your question?
