Question

A man exerts a force of 200 N in pulling a cart at a constant speed of 16 m s−1. Calculate the power spent by the man.​

Answer 1

Answer:

Force=200N, velocity=16ms−1

Power=force×

velocity=200N×16ms−1=3200W

Answer 2

★ Given :

• ➼ Force = 200 N

• ➼ Velocity = 16m s⁻¹

★ Find :

• ➼ The power spent by the man.

★ Formula Used :

• ➣ Power = Force ༝ Velocity

★ Solution :

• ➣ 200 N ༝ 16m s⁻¹
• ➣ 3200 W

☯ Therefore,

• Hence, the power spent by the man is 3200 W.
