Assume that the energy lost was entirely due to friction between the ball and the PVC pipe track. For the calculation in this question, you may ignore uncertainties.i. [1.0 pts] Calculate the total energy lost from your measurements. Show your work.ii. [0.25 pts] Assume that the total length of the PVC pipe is 1 meter. Use this length and the energy lost (from part i) to compute the average force of friction between the ball and the PVC pipe.iii. [0.5 pts] Calculate the coefficient of friction between the ball and the PVC pipe.iv. [0.25 pts] The coefficient of kinetic friction between steel and PVC is 0.38. How does your coefficient of friction compare?
