Question

A circular wheel is rotating at the rate of
25 revolutions per minute. If the radius of
the wheel is 40 cms, then the distance
covered by a point on the rim in one
second. (Take ñ = 3.1416 ).​

Answer 1

Answer:

Radius of wheel, R=0.25m

Number of revolution per minute, n=15

Angular velocity, v=

60

n×2πr

=

60

15×2π×0.25

=

8

π

ms

−1

Hence, angular velocity is

8
