A wheel that is rotating at 33.3 rad/s is given an angular acceleration of 2.15 rad/s 2. Through what angle has the wheel turned when its angular speed reaches 72.0 rad/s

The angle through which the wheel turned is 947.7 rad.

Explanation:

initial angular velocity, = 33.3 rad/s

angular acceleration, α = 2.15 rad/s²

final angular velocity, = 72 rad/s

angle the wheel turned, θ = ?

The angle through which the wheel turned can be calculated by applying the following kinematic equation;

Therefore, the angle through which the wheel turned is 947.7 rad.
