Question

A particle in a circular motion with acceleration alpha=0.2rad/s at t=5s,then the angular displacement is

Answer 1

Answer:

1.23 this are the answer

mark me branlisr

Answer 2

Answer:

Given that Angular acceleration of the particle = α=0.2rad/s

2

Using Ist equation of motion for circular motion we get

ω=ω

0

+αt

Since particle is at rest initially ∴ω

0

=0

⟹ω=αt=0.2×10=2rad/
