In the accompanying figure, determine (a) The work done by the force F acting at an angle

Question:

In the accompanying figure, determine
(a) The work done by the force F acting at an angle of θ = 20o in moving the block of mass 10 kg by a distance of 3 m if μs = 0.5.
(b) What is the sign of the work transfer if the block were treated as a system (1: positive; 2: negative)?
(c) If the block comes to rest at the end of the process, describe what happens to the work done by the force?
