A light shines from the top of a pole 50 ft high. A ball is dropped from the same height from a point 40 ft away from the light. How fast is the shadow of the ball moving along the ground 1 sec later? (Assume the ball falls a distance s equals 16 t squared in t sec.) A horizontal x-axis labeled shadow is labeled 0 on the left at the location of a 50 foot high pole and 40 to the right at the location of a vertical line segment. The vertical line segment has an open dot at the top labeled Ball at time t equals 0. A line segment that falls from left to right starts at the top of the pole and ends on the x-axis at a point labeled x(t) to the right of the vertical line segment. The point where the two line segments intersect is marked with a closed dot labeled 1 second later. An arrow on the x-axis points to the left between x(t) and 40. 1 Ball at time t=0 sec later 40
