How much power is expended if you lift a 60 n crate 10 meters in 1 second?
a. 0 w
b. 6 w
c. 10 w
d. 60 w
e. 600 w?

Respuesta :


It's P =W/t is equation 1 . Since W=F×S.. put it in equation 1 ,we get P=FS/t. Put F =60N , S=10m and time =1 s in equation 1. Then we have P=60×10/1s which is 600 Watts. So power of the body is 600Watts

The power expended in lifting the crate thrrough the given distance and time is 600Watts.

Work and Power

Power is simply referred to as the quantity of energy transferred per unit time.

It is expressed as;

P = W / t

Work is simply the measure of energy transfer that takes place when an object is moved over a given distance by a push or pull force.

It is expressed as;

W = F × d

Hence;

Power P = (  F × d ) / t

Given the data in the question;

  • Weight of crate F = 60N = 60kgm/s²
  • Distance covered d = 10m
  • Time elapsed t = 1.0s
  • Power P = ?

To determine the power expeneded, we substitute our given values into the expression above.

P = (  F × d ) / t

P = (  60kgm/s² × 10m ) / 1.0s

P = (  600kgm²/s² ) / 1.0s

P = 600kgm²/s³

P = 600Watts

Therefore, the power expended in lifting the crate thrrough the given distance and time is 600Watts.
