Question

A race car travels in a circular track of radius 200m. If the car move with a constant speed of 80 m/s, find (a) its angular velocity and (b) its tangential acceleration

Answer 1

Answer:

(a) 0.40 rad/s

(b) 0 m/s

Explanation:

Since the car is moving at a constant speed, the tangential acceleration of the car is 0 m/s.

To find its angular velocity, we use the equation ω = v/r.

Therefore, the angular velocity ω = 80/200 = 0.40 rad/s.
