Question 2 This question is a short free-response question. Show your work for each part of the question. Block Submit Person Ice A person pushes a large block on a horizontal ice surface in a straight line to the right with constant speed, as shown above. The mass of the block is 10 kg and frictional forces between the block and the ice are negligible. However, the block has a wide cross-sectional area such that air resistance acting on the block cannot be neglected. The opposite is true for the person: air resistance on the person is negligible, but the person's shoes do not slip on the ice. The table shows the force exerted by the person on the block for several values of constant speed. Force of person's push (N) Constant speed of block (m/s) +0.05 20 1.25 40 2.51 60 3.73 80 5.00 (a) A student claims that the data show that the magnitude of the force of air resistance is proportional to the speed of the object, within experimental uncertainty.

Learning outcome Fundamental./ evaluation Fundamental.7 deals with the equation of motion. The use of the equation of motion to solve this problem is mandatory. Solution using other approaches (conservation of energy...) will be automatically considered false. For the problem related to Fundamental.7 sketches of the system showing: • the respective velocity and acceleration and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. 2 Lft The 2-lb man lies against the cushion for which the coefficient of static friction is 0.6.

4) Activity 5: Check for Understanding (5 mins) Student Engagement (SE) Think-Pair-Share Solve the problem. 1. You are working as a delivery person for a dairy store. In the back of your pick-up truck is a crate of eggs. The dairy company has run out of bungee cords, so the crate is not tied down. You have been told to drive carefully because the coefficient of static friction between the crate and the bed of the truck is 0.6. You are not worried, because you are traveling on road that appears perfectly straight. Due to your confidence and inattention, your speed has crept upward to 45 miles per hour. Suddenly you see a curve ahead with a warning sign saying, "Danger: unbanked curve with radius of curvature 35 m". You are 15 m from the beginning of the curve. What can you do to save the eggs: (a) take the curve at 45 mi/h, (b) brake to a stop before entering the curve to think about it, or (c) slow down to take the curve at a slower speed? Discuss these options in your group and…
