I did half the questions for this assignment, please help me out for rest of the questions below:




1. A woman pushes a lawnmower forward with a force of 125 N for a distance of 15 m as shown. The force makes an angle of 340 with the horizontal. At the same, a constant 50.0N frictional force on the lawn mower from the ground opposes the motion. Calculate the total amount of work done on the lawn mower.

Include a free-body diagram. (3 Marks)4. What is the work-energy theorem? State it in your own words, and give 2 examples that relate it to different forms of energy. (4 Marks)6. A 75g ball is dropped onto a spring that is fixed to the ground. The spring is 35cm long at equilibrium. If the ball is dropped from 1.5m above the spring, and the spring constant is 350 N/m, how much will the spring compress when the ball comes to a stop at maximum compression? (use the ground as your reference point) (6 marks)
