Question

If force is 500 N and instantaneous velocity is 20 m/s, what is the instantaneous power?

• A. 10,000 W
• B. 5,000 W
• C. 500 W
• D. 2,000 W

Hint:

Power is the product of force and velocity. It tells you the rate at which work is done.

Answer 1

The Correct Option is B

The instantaneous power is given by the formula: \[ P = F \cdot v \] where \( F \) is the force and \( v \) is the velocity. Substituting the given values: \[ P = 500 \, \text{N} \times 20 \, \text{m/s} = 10,000 \, \text{W} \]
