The wheel of toy car rotates about axis. It slows down from 400 rps to 200 rps in 2s. Then its angular retardation in

\mathrm{rad}{\mathrm{s}^{ - 2}}

is

View answer and explanation

Correct option: A

200

\pi

Option A (200π) is correct because angular retardation is the change in angular velocity divided by the time interval.
