Please help with this question, it comes with a few subparts. PLEASE HELP. **Physics Problem Set: Friction and Forces****(a)** What is the maximum frictional force (in N) in the knee joint of a person who supports 75.0 kg of her mass on that knee?[Input box for answer] N**(b)** During strenuous exercise it is possible to exert forces to the joints that are easily ten times greater than the weight being supported. What is the maximum force of friction (in N) under such conditions? (The frictional forces in joints are relatively small in all circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pain.)[Input box for answer] N---**Suppose you have a 112-kg wooden crate resting on a wood floor. (\(\mu_k = 0.3\) and \(\mu_s = 0.5\))****(a)** What maximum force (in N) can you exert horizontally on the crate without moving it?[Input box for answer] N**(b)** If you continue to exert this force (in m/s\(^2\)) once the crate starts to slip, what will the magnitude of its acceleration then be?[Input box for answer] m/s\(^2\)---This problem set explores the concepts of friction and force, examining how they apply in both biological contexts (such as knee joints during exercise) and physical scenarios (like moving a crate). The exercises require understanding static and kinetic friction and how forces translate into acceleration.

Given: mass=75 kg To Find: F1, F2

a) What is the maximum frictional force (in N) in the knee joint of a person who supports 75.0 kg of her mass on that knee? N (b) During strenuous exercise it is possible to exert forces to the joints that are easily ten times greater than the weight being supported. What is the maximum force of friction (in N) under such conditions? (The frictional for circumstances except when the joints deteriorate, such as from injury or arthritis. Increased frictional forces can cause further damage and pain.) uppose you have a 112-kg wooden crate resting on a wood floor. (H = 0.3 and u, = 0.5) (a) What maximum force (in N) can you exert horizontally on the crate without moving it? N (b) If you continue to exert this force (in m/s) once the crate starts to slip, what will the magnitude of its acceleration then be?

Can you please clarify how to do these graphs? I think I've got the first two done, but then they start getting complicated, and I my scales are messed up. I have a program I can run to look at the answers, so getting the correct answer is not the problem, but can you tell me how to do them? And then I don't fully understand how to describe them either as I am instructed to do. Thank You!
