Question

An object's position as a func of time is given by ; x(t) = - 200 (( t + 1 ) ^ - 1) + 6t^2.  (Assume constants have proper SI Units) 

An object's instantaneous velocity at t = 3.00 seconds is 45.5 m/s

What is the object's average velocity between t = 0 and t = 3.00 seconds? 

Answer is 68.0 m/s^2

What is the object's average acceleration between t = 0 and t = 3.00 s 

Answer : - 50.5 m/s^2
