Question

A certain motor is capable of doing 3000 J of work in 11 s . What is the power output of this motor?

Short answer

The power output of this motor is 272.2 W.

Step-by-step solution

Definition of Work and Time

The work is the energy delivered to or from an item by applying force along a displacement in physics.

The time is defined by physicists as the flow of events from the past through the present and into the future.

Given Information

• The motor is capable of doing 3000 J of work.
• The time taken is 11 s .
• To find the power output of this motor.

Finding power output

Divide the work, W and time t to determine the motor's power output.

$P=\frac{W}{t}$

Substitute W=3000 J and t=11 s into the formula.

$$\begin{gathered} P=\frac{3000J}{11s} \\ =272.2W \end{gathered}$$

Therefore, the power output of the given motor is 272.2 W.
