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

=>  

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
