Please refer to the picture with the formulas and constants that need to be used in this problem. Harzan wants to swing from one bank of the river to the other using an overhaning vine. As he swings, he traces out an arc of a circle.  Part 1) Please draw and label a free body diagram of Harzan at the bottom of the swing.  Answer: we have to discuss the motion of the swinging person Part 2) What forces act as the radial force in the circular motion?  Answer: In the radial direction centrifugal force will act as a source of tension Part 3) Is this uniform circular motion? Explain  Answer: The motion is similar to that of a pendulum, thus the vine-swinger system acts like a physical pendulum, the motion will not be uniform circular.  Part 4) The vine is 6.2 m long, and Harzan's mass is 85 kg. At the bottom of his swing, he is travelling at 4.3 m/s. What is the magnitide of the radial acceleration that Harzan experiences?  Part 5) How much tension must the vine support in order to safely…

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…

Two students are conducting an experiment in which they are trying to find a relationship between the angle of incline of a ramp and the final speed a car reaches when rolling down the ramp. In order to collect their data, the students must determine the final speed of the car at the bottom of the ramp. The students discuss how they should determine this speed. Student 1: “We need to measure the length of the ramp and the time it takes the car to roll down it. Then we can divide the total distance by the total time to find the final speed.” What is wrong with Student 1’s method for determining the final speed?   This method will only determine the average speed, not the final speed. This method will determine the acceleration, not the final speed. This method does not account for the height of the ramp. This method does not take into account the angle of the ramp.
