Question

A body travels 1/4 of circumference in 2 sec, find the speed in Radian/sec​

Answer 1

We know that,

Acceleration = $\frac{\rm{Change~in~velocity}}{\rm{Time~taken}}$

Use, this value for answer...!!

Answer 2

In uniform circular motion, angular velocity () is a vector quantity and is equal to the angular displacement (Δ, a vector quantity) divided by the change in time (Δ). Speed is equal to the arc length traveled (S) divided by the change in time (Δ), which is also equal to ||R
