 When an object is dropped on a certain earth-like planet, the

distance it falls in t seconds, assuming that air resistance is negligible,

When an object is dropped on a certain earth-like planet, the distance it falls in t seconds, assuming that air resistance is negligible, is given by s(t) =1st2 where s(t) is in feet. Suppose that a medic's reex hammer is dropped from a hovering helicopter. Find (a) how far the hammer falls in 5 sec. (b) how fast the hammer is traveling 5 sec after being dropped, and (c) the hammer's acceleration after it has been falling for 5 sec. (a) The hammer fails I] feet in 5 seconds. (Simplify your answer.)
