Question

A sandbag is dropped from a balloon at a height of 60 meters when the angle of elevation to the sun is 30° (see figure).

The position of the sandbag is

s(t) = 60 − 4.9t^{2}.

Find the rate, in meters per second, at which the shadow of the sandbag is traveling along the ground when the sandbag is at a height of 11 meters. (Round your answer to two decimal places.)
