Question
A body rotating with uniform angular acceleration covers 100 π (radian) in the first 5 s after the start. Its angular speed at the end of 5 s ( in radian/s) is
Joshi sir comment
initial angular velocity = 0
so use θ = 1/2 αt2
and ω = αt
Read 1 Solution.
α = ω/t => ω= αt = 100π X 5 = 500π rad/s (ans)
