A 11 m tall streetlight is positioned 16 m away from a vertical wall. Timothy throws a tennis ball directly towards the wall with a speed of 16.6 m/s. Assuming that the ball travels on a perfectly horizontal path 1.5 m above the ground, at what rate is the shadow of the ball moving up the wall when it is 2 m from the wall?
