An automobile tire with a radius of 0.30 m starts at rest and accelerates at a constant angular acceleration of 2.0 rad/s2 for 5.0 s. What is the angular displacement of the tire?

The value is

Explanation:

From the question we are told that

   The radius is  

   The acceleration is

    The time taken is

Generally the angular displacement is mathematically represented as

Here s is the linear distance covered by the tire which is mathematically represented as

Here  u is 0 given that the car started from rest and

So

So
