Answer:

370.3J

Explanation:

A 10 kg ball is rolled to the top of a hill 37 m high using 4000 J of work. How much energy was lost due to heat?

Step one:

given data

mass m= 10kg

height of the hill= 37m

work done= 4000J

Step two:

The quantity of energy loss due to heat is the same as the difference in the  potential energy possed by the mass and the work done

PE= mgh

PE=10*9.81*37

PE= 3629.7J

Hence the energy loss is

= 4000-3629.7

=370.3J
