feet away from the side of the building. The height y of the

ball at time t is given by y(t) = 64 − 16t2. How fast is the

shadow of the ball moving along the ground after 1 second?

**MathMate**, Monday, September 27, 2010 at 10:19amThe velocity of the ball after time t is given by:

y'(t)=-32t

The shadow cannot be traced unless the position of the sun or light source is known.
