Joanie, a 22 y/o female, goes to the ED. She has not been feeling well for several weeks, has lost 8 pounds in the last 2 weeks, and feels thirsty and urinates more frequently than ever before. Her blood sugar in the ED is 528 and her PH is 7. At this time, there is concern that she is probably in

These questions must be completed before continuing to the second part of the test containing the last two questions. These three questions do not require you to do any hand writing or the use of scratch paper. Your attention should remain on the screen while answering these questions. Make sure that these questions are complete before moving on to Part 2. Question 1 (10 marks) a) Describe a situation that demonstrates Newton’s first law of motion. b) Describe how Newton’s second law connects the motion calculations that we did in Unit 1 to the dynamics concepts that we are looking at in Unit 2. c) How does a person jumping up into the air demonstrate Newton’s third law of motion? Question 2 (10 marks) a) Describe how you could determine the net force for an object using a free body diagram. b) For objects that are sliding across the ground (on Earth), how does the force of gravity influence the force of friction that they are experiencing? Question 3 (10 marks) a) If an object is placed on a ramp and starts to slide down towards the bottom of the ramp, what force(s) determine it’s acceleration? b) Why would increasing the angle of a ramp increase the acceleration that an object that is sliding down the ramp experiences?

These two questions must be completed using paper, a writing utensil, and a calculator (you can use the desmos online calculator if you would like). In the text box for this question you will type a single statement for each question that describes your final answer. Immediately BEFORE submitting the test. Show the paper(s) with your calculations to the camera. Make sure to hold them up long enough so that the camera is able to focus. Immediately AFTER submitting the test. Take pictures of your written work and email them to me with the subject “Unit Test 2 Answers”. Question 4 (10 marks) A 18kg object is sliding horizontally across the ground with a coefficient of friction of 0.45. If the applied force is 148N [23 degrees above horizontal] solve for the acceleration of the object. Question 5 (10 marks) A 6kg object is sliding down a ramp that has a 34 degree incline. If the coefficient of friction is 0.25, solve for all of the forces acting on the object and it’s acceleration.
