7. (10 pts.) Of 100 boxes of fuses containing 5 fuses per box, 20 boxes contain fuses from factory A, 30 boxes from factory B, and 50 boxes from factory C. Fuses from A are on average 5% detective; from B 4% defective, and from C, 2%. A box is selected at random, and a fuse in it is tested and found to be defective. What are the probabilities that it was produced at A, B, or C respectively?

7. (20 pts) A force of 50 N is used to move a 5 kg box 30 m across a level floor. a. How much work was done on the box? b. If the movement takes 10 seconds, what is the average velocity of the box during the move? c. What is the average kinetic energy of the box during the move? d. What is the change in potential energy as a result of this move?
