Dear student as you have asked a question with multiple subparts, according to Bartleby policy we can solve the 1st 3 subparts for you, To get the answer to the remaining subpart please repost the entire question by mentioning the subpart you wanted us to solve.
Calculation of work done is very easy we just have to find three thing
1. Force for which we want to find work done
2. how much distance it traveled
3. angle between force and displacement.
