What is the angular displacement made by...

What is the angular displacement made by a particle after `5s`, when it starts from rest with an angular acceleration `0.2` and `s^(-2)` ?

A

4rad

B

1 rad

C

2.5 rad

D

5 rad

Text Solution

Verified by Experts

The correct Answer is:
C
From equation of circular motion `omega = 0`
` theta = omega t + 1/2 prop t^2`
` theta = 1/2 prop t^2 = 1/2 xx 0.2(5)^2 = 2.5 rad `
