Question 2 A This question is a short free-response question. Show your work for each part of the question. Block 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. Use physics principles to explain whether the claim is correct.

Learning Objectives: In this assignment students will use Newton’s laws and solvesystems of symbolic equations to find quantities of motion such as position, velocity,acceleration and time. Students will represent information in multiple ways. Studentswill make predictions and assess their work.Problem Statement: An object of mass m rests at the top of a smooth slope ofheight h, length L and angle ?. The coefficient of kinetic friction ??. A very smallpush overcomes static friction, and the object begins to slide down the slope.Using your knowledge of kinematics, determine a symbolic expression for the object’sspeed when it reaches the bottom of the hill. This should be in terms of some of all ofgiven/known variables m, h, L, g, ? and ??. Check the physical units of yourexpression.

If you were performing this experiment in an in-class laboratory, you would be given one or more small iron balls. These would be utilized with a variant of the Free-Fall apparatus shown in the graphic below. (INSERT PICTURE HERE) You would first raise the upper black clamp to the desired height above the middle clamp. Then you would place the ball firmly in the upper clamp. Next, you would turn on the timer and adjust its initial reading to zero. After you release the ball, it falls towards the middle clamp. When it encounters this clamp, the timer stops and you can read the time of fall. Results are usually within 10% of the standard value of g. Here, in this online version, I will supply values of height (h) and time (t). First, calculate the average time (tav) for each height and use it as described next. You will use the third equation above to calculate the value of gravitational acceleration (g) in each case. Then, you will determine the…
