###### Problem Details

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 ]i + [2.00 m/s + (0.550 m/s2 )t]j.
(a) What is ax(t), the x-component of the acceleration of the car as function of time?
(b) What is ay(t), the y-component of the acceleration of the car as function of time?
(c) What is the magnitude of the velocity of the car at t  =7.01 s?
(d) What is the direction (in degrees counterclockwise from +x-axis) of the velocity of the car at  t=7.01 s?
(e) What is the magnitude of the acceleration of the car at t  =7.01 s?
(f) What is the direction (in degrees counterclockwise from +x-axis) of the acceleration of the car at t=7.01 s?
