part one:
an 18.7 kg block is dragged over a rough, horizontal surface by a constant force of 104 n
acting at an angle of 26.6◦
above the horizontal. the block is displaced 51.9 m, and the
coefficient of kinetic friction is 0.223.
find the work done by the 104 n force. the acceleration of gravity is 9.8 m/s^2.
answer in units of j.

part two:
find the magnitude of the work done by the
force of friction.
answer in units of j.
