can you please help me with this assignment, please show all the work.

This is Physics 20 (grade 11)- Module 6 - Lesson 3 - The Work-Energy Theorem

Question 1 In the online lesson you watched several videos showing a lab activity. The purpose of the lab Not yet answered activity was to demonstrate the CHANGE in the POTENTIAL ENERGY of an object as a function Marked out of of its position. 7.00 The lab ALSO explored the concepts of CONSERVATIVE VS. NON-CONSERVATIVE forces. Flag question Answer the following questions based on your lesson readings and the lab activity videos. a) In the videos, you should have seen a graph showing the FORCE applied to the object as a function of the DISTANCE the object moved. If you watch closely, you will notice that the FORCE is non-zero when the object moves up and down, but the force is ZERO if the object moves horizontally. Explain this observation --> Why doesn't the graph show net force for motion in the horizontal axis? (1 mark) b) Consider an object moved along the path shown in the following picture. It starts on the ground at 0 m, then moves up to a height of 2 m by following the curved pathway. Sketch two graphs:First, a graph of F(cos O) vs distance (2 marks) Second, a graph of potential energy vs. distance (2 marks) Use the online videos as guides for how to create these graphs. Assume there is no friction. 2 m Om c) Explain how the graphs you drew in "b" would CHANGE if non-conservative forces acted over the whole distance of the object's motion. (2 marks)Question 2 Consider the following system: Not yet answered Marked out of 4.00 Flag question O A 1.40 m BMass A = 2.40 kg and Mass B = 1.50 kg. The system is allowed to move freely without friction. UPLOAD two graphs showing the system energy as a function of the POSITION of the masses as they move: Graph 1: Plot the energy of the system as a function of the change in position of the masses assuming no friction. Graph 2: Plot the energy of the system as a function of the change in position of the masses assuming friction is present. For each graph show 3 lines: Potential energy of the system, Kinetic energy of the system, and Mechanical energy of the system. Paragraph B IE
