Let the PVC pipe be at a height, H.

Time of fall, t:

$\overline{){\mathbf{t}}{\mathbf{=}}\sqrt{\frac{\mathbf{2}\mathbf{H}}{\mathbf{g}}}}$

###### Problem Details

Assume that the energy lost was entirely due to friction and that the total length of the PVC pipe is 1 meter. Use this length to compute the average force of friction (ignore uncertainties). Show your work.

Mass of ball: 16.3 g

Predicted range: 0.3503 m

Actual range: 1.09 m
