33) This question asks us to find the power produced by the given torque. In general, we can write the formula for power.

Where P is power, W is work, t is time, F is force, d is displacement, t is time, and v is velocity

For this question we want to find the instantaneous torque. However, we will use the angular motion equivalent for F and v.

Where P is power, W is work, t is time, 𝛕 is torque, θ is angular displacement, and ω is angular velocity

Answer: B
