A remote controlled car is moving in a vacant parking lot. The velocity of the car as a function of time is given by v = [5.00 m/s - (0.0180 m/s3) t^2 ]i+[2.00 m/s + (0.550 m/s2) t ]j.

a) What are ax (t) and ay (t), the x - and y - components of cars acceleration as a function of time?

b) What are the magnitude and direction of the velocity of the car at t = 8 sec?

c) What is the magnitude and direction of cars acceleration at t=8 sec
