Answer» body is released to fall under the INFLUENCE of gravity. Its approximate equation of MOTION is given by S(t) = 4.9t².To find:Instantaneous Velocity at t = 5 sec.Calculation:Velocity FUNCTION of an object can be derived by first order DIFFERENTIAL equation of the displacement function of the body.So, instantaneous velocity at time = 5 sec:So, final answer is:
