an object moves along the x-axis according to the equation x = 3.00t2 + 2.00t – 3.00, where x is in meters and t is in seconds. determine (a) the average speed between t=2.00s and t=3.00s, (b) what is the instantaneous speed at t=2.00s and t=2.50s, (c) the average acceleration between 2.00s and 3.00s, and (d) the instantaneous acceleration at t=2.00s and t=3.00s. (e) at what time is the object at rest?
