Question

A grindstone rotates with constant angular acceleration. Which equation relates angular displacement, initial angular velocity, time and acceleration?
Options
A θ = ωt
B θ = ωt + ½αt²
Correct Answer
C θ = αt
D θ = at²
Correct Answer

Option B is the correct answer.

Detailed Explanation

Angular displacement equals initial angular velocity times time plus half angular acceleration times time squared.

Hint

Rotational analogue of s = ut + ½at².
