Answer 1

Answer:

Explanation:

so, since

force=100n

height1=5m

height2=3m

1)work =force*displacement

          =100N*5m

            =500J.

2)work=100*3

           =300J.

3)the difference in the work done=500J-300J=200J

=200J is the energy used in doing work against the force of friction between the block and the slope which will appear as heat energy.
