Calculus

A lamppost supports a light 20 meters above the ground. Twelve meters from the lamppost, a ball that is being held 20 meters above the ground is released and allowed to free-fall to the ground. The ball’s shadow, caused by the light at the top of the lamppost, is moving along the level ground toward the base of the lamppost. How fast is the shadow moving one second after the ball is released?
