Question

12) A 10.0 kg box is pushed up a ramp from the ground to a height of 1.00 m. The push force is
parallel to the ramp.
a. What is the change in potential energy of the box?
b. How much work was done in moving the box?

Answer 1

Change in potential energy
= mgh
= (10.0)(9.81)(1.00)
= 98.1 J

By conservation of energy, Work done
= change in potential energy of box
= 98.1 J
