Question

How much power is required to push a box 4.0 m with a force of 150 N in 2.5s?

A. 15W
B. 1500W
C. 240W
D. 94W

Answer 1

Answer

the anser is (C) as 240 Watt

Explanation

As we know that

$Power= Work/Time$

$Work = Force * Distance$

As given in question

Force = 150 N

Distance = 4m

Then work is

$Work = 150 * 4 Nm$

$Work = 600 Nm$

$Power= 600/2.5$

$Power= 240 Watt$

So the answer is 240 watt
