Answer:

113.4 newton-meters (or Joules)

Explanation:

You need to know that potential energy PE is given by the formula ...

PE = mgh

where m is mass, g is the acceleration due to gravity, and h is the height above the ground. Then the difference in potential energy is ...

ΔPE = m(g1)h -m(g2)h = mh(g1 -g2)

ΔPE = (1.8 kg)(10 meters)(10 N/kg -3.7 N/kg) = 113.4 N-meters
