A wheel rotating

Given data

Α = angular acceleration =50 rad/sec²

t = time = 5 sec.

θ = total angle rotated

= 50 * 2π radians.

Total angle rotated at the end of 5 seconds

Using the second equation of kinematics.

Where,

θ = total angle rotated

= initial angular velocity

t = time period

=angular acceleration

rad/sec²

We know that, 1 revolution = 2π rad.

Revolutions/s

Revolutions/sec².
