Answer #1

Radius of the wheel = R = 1 m

Constant angular speed of the wheel = = 2 rad/s

Number of revolutions made by the wheel = n = 20 rev

Angle through which the wheel rotates =

= 125.66 rad

Time taken by the wheel to complete 20 rotations = T

T = 62.83 sec

Time taken by the wheel to complete 20 rotations = 62.83 sec
