Assessment 11.Topic: Newton's Laws of Motion and ApplicationsShow your complete solutions. Include necessary diagrams. 11. Consider the system shown in Figure 3. Block A weighs 45.0 N and block B weighs 25.0N. Once block B is set into downward motion, it descends at a constant speed. (a) Calculatethe coefficient of kinetic friction between block A and the tabletop. (b) A cat, also of weight45.0 N, falls asleep on top of block A. If block B is now set into downward motion, whatis its acceleration (magnitude and direction)?AFigure 3B

Consider applying Newton's law to a man riding an elevator (perhaps calculating his acceleration). Which of the following forces must be considered? Choose all that apply. 1.) The force that the man's feet exert on the floor of the elevator. 2.) The force of gravity on the elevator. 3.) The force of the elevator cable exerts on the elevator car. 4.) The force that the elevator floor exerts on the man's feet. 5.) The force of gravity on the man. 6.) The force that the man's head exerts on his neck.
Explain how to get the correct answer. It is not enough to just say what the correct answer is; you must explain the thought process behind how someone would get that answer. Explain what mistake you made and, more importantly, something concrete you can do in the future to keep from making this mistake again.
Hello can you guys explain why the answer has earth in for question 11 and for 12 explain why it's newton's first law?

PHY 150 Newton's Second Law – Part 1 Day 1 of 2 1. We will be accelerating a cart on a track by inclining the track at a small angle. Initial position Final position 2. Draw a free-body diagram for the cart. Label your diagram with a set of coordinate axes (x,y). [Hint: What direction does the cart accelerate? Make that direction the positive x-direction.] 3. Using your free body diagram, find the net force on the cart? 4. Write Newton's 2nd law for the cart. Plug in the net force from #3. 5. Solve the equation in #4 for the acceleration of the cart. You then have a hypothesis (prediction) for the acceleration. [HINT: There are some measurements you need to make in order to calculate the acceleration.]
