A school bus drives in a straight line down a road. Its position x from a stop sign is given as a function of time by the following equation: x(t)=At^2-Bt^3, where A = 2.50 m/s^2 and B = 0.0855 m/s^3 . Use this information to calculate:

a. the bus’s average velocity from t = 0 to t = 2.00 s

b. the bus’s instantaneous velocity at t = 0 and t = 2.00 s

c. the bus’s average acceleration from t = 0 to t = 2.00 s

d. the bus’s instantaneous acceleration at t = 0 and t = 2.00 s
