Question

PHYSICS
A particle moves along a circular path of length 15cm with a constant angular acceleration of 4rad/s
2
. If the initial angular speed of the particle is 5rad/s, find the angular displacement of the particle in 5s. (in rad)

Answer 1

Answer:

ANSWER

Angular displacement equation is given by

θ

t

=ω

Given that ω

0

=5 rad/s, α=4 rad/s

2

and t=5sec

⇒θ

t

=5×5+

⇒θ

t

=75 rad
