Question
A light shines from the top of a pole 40 ft high. A ball is dropped from the same height from a point 20 ft away from the Ball at time t=0 1 sec later light. How fast is the shadow of the ball moving along the ground sec later? (Assume the ball falls a distances = 16t2 40-ft in t sec.) pole Shadow 20 x(t) The shadow is moving at a velocity of ft/sec. (Type an integer or a decimal.)
