When an object is dropped, the distance it falls in t seconds, assuming that air resistance is negligible, is given by s(t) = 1612 where s(t) is in feet. Suppose that a medic's reflex hammer is dropped from a hovering helicopter. Find (a) how far the hammer falls in 3 sec, (b) how fast the hammer is traveling 3 sec after being dropped, and (c) the hammer's acceleration after it has been falling for 3 sec. (a) The hammer falls |feet in 3 seconds 144 ft S ( + ) = 16 A2 (Simplify your answer.) (b) The hammer is traveling f/sec 3 seconds after being dropped. (Simplify your answer.) ( a) s ( 3 ) = 16:32 (c) The hammer's acceleration is fu/sec/sec after it has been falling for 3 sec. (Simplify your answer.) = 16 - 9 b . V = s' = 32 + = 144 5+ + = 25
