Question
A box with mass of 6.0 kg is lifted ( without acceleration) through a height of. 2.0, in order to place it upon the shelf of a closet. A. What is the increase in potential energy of the box B. How much work was required to lift the box to this position A box with mass of 6.0 kg is lifted ( without acceleration) through a height of. 2.0, in order to place it upon the shelf of a closet. A. What is the increase in potential energy of the box B. How much work was required to lift the box to this position A. What is the increase in potential energy of the box B. How much work was required to lift the box to this positionExplanation / Answer
A)
PE = mgh
where m = 6 kg
g = 9.81 m/s^2
h = 2 m
PE = 6 kg x 9.81 m/s^2 x 2 m
PE = 117.72 J
B)
work done = potential energy
work done = 117.72 J
