Question

A 62 kg box is lifted 12 meters off the ground. How much work was done?
A) 5.17 J
B) 72.91 J
C) 517.0 J
D) 7291.2 J

Answer 1

As per work energy theorem,
W=U (potential energy)

W=mgh
=62×9.8×12
=7291.2 J

so your answer is D) 7291.2 J


hope it helps u^-^

Answer 2

HERE IS YOUR ANSWER

the work done will be equal to the potential energy at 12 meter

potential energy = mgh

= 62 × 9.8 × 12

= 7291.2 J = work done

Therefore the answer is D)

HOPE THE ANSWER IS CORRECT
