A car is traveling at an angular acceleration of 0.04 rad/s2 on a circular part of a road. If the radius of the circular part is 200m, find the net acceleration of the car when the angular velocity of the car is 0.2rad/s.

Answer:

8 m/s²

Explanation:

α = 0.04 rad/s²

w = 0.2 rad/s

t = ?

α = w/t

===> t = w/α = 0.2/0.04 = 5 sec

v = wr = 0.2 × 200 = 40 m/s

the net acceleration a = v/t = 40/5 = 8 m/s²
