Question

62 kg box is lifted 12 meters off the ground. How much work was done? A) 5.17 J B) 72.91 J C) 744.0 J D) 7291.2 J

Answer 1

62 x 9.8 x 12= 7 291.2! Hope this is helpful!

Answer 2

Answer : The correct option is, (D) 7291.2 J

Solution : Given,

Mass of the box = 62 Kg

Distance = 12 m

Formula used :

$W=F\times D\\\\W=m\times g\times D$

where,

W = work done

F = force

m = mass of box

g = acceleration due to gravity = $9.8m/s^2$

D = distance

Now put all the given values in the above formula, we get the work done.

$W=(62Kg)\times (9.8m/s^2)\times (12m)=7291.2J$

Therefore, the work done was, 7291.2 J
