Question

An object moves along the x axis according to the equation x 3.102 2.00t 3.00, where x is in meters and t is in seconds. (a) Determine the average speed between t 2.40 s and t-4.20 s. The average speed is the distance traveled divided by the time. Is the distance traveled equal to the displacement in this case? m/s (b) Determine the instantaneous speed at t-2.40 s m/s Determine the instantaneous speed at t-4.20 s m/s (c) Determine the average acceleration between t = 2.40 s and t-4.20 s. m/s2 (d) Determine the instantaneous acceleration at t 2.40 s. m/s Determine the instantaneous acceleration att 4.20 s.
