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
