The position of a particle moving along the x axis is given in cm by x = 8.25 + 2.50t^3, where t is in seconds. Consider the time interval t = 2.00 sec to t = 3.00 sec.
(a) Find what is the average velocity?
(b) Find the instantaneous velocity at t = 2.00sec.
(c) Find the instantaneous velocity at t = 3.00sec.
(d) Find the instantaneous velocity at t = 2.50sec.
(e) Find the instantaneous velocity when the particle is midway between its positions at t = 2.00 sec and t= 3.00 sec.
