Answer:
force does work when it produces a displacement
if the displacement is in the direction of force work is positive
if the displacement is in the opposite direction work is negative
work done by force is zero if no displacement is produced on the line of action of the force
work done is 50x13.8 cos 0degrees= 69 joules
work done against gravity= mass * g* displacement * cos90 degrees
=4550 joules
part of force=78cos27=69.4985
work done is fcos 27 *displacement=8687.31361 joules
