Question:

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)t²]î + [2.00 m/s + (0.550 m/s²)t]ĵ.

(a) What are and α_x(t) and α_y(t), the x- and y-components of the velocity of the car as functions of time?

(b) What are the magnitude and direction of the velocity of the car at t = 8.00 s?
