Question

A car is going with constant speed on a circular path. If it starts from point A at t = 0 and reaches diametrically opposite point B after 2 sec then find its angular velocity.

• A.
• B.
• C.
• D.

Answer 1

Answer: (B)

In going from A to B the car is displaced by an angle of ${180}^{\circ }$.

So, angular displacement = $\pi$ radians

Time = 2 sec

Angular velocity = $\frac{angulardisplacement}{time}$
$\omega =\frac{\pi }{2}\frac{rad}{sec}$
