An object is released from rest (its initial velocity is zero) from the Empire State Building at a height of 1250 ft above street level. The height of the object can be modeled by the position function s = f (t) = 1250 ā 16t2 (a) Find the objectās instantaneous velocity at time t = 6 s. (b) Verify that the object is still falling at t = 5 s.
