The question is incomplete. The complete question is :
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 (for this calculation, you may neglect uncertainties).
Mass of the ball : 16.3 g
Predicted range : 0.3503 m
Actual range : 1.09 m
Solution :
Given that :
The predicted range is 0.3503 m
Time of the fall is :
...........(i)
...........(ii)
Dividing the equation (ii) by (i)
∴
Now loss of energy = change in the kinetic energy
If f is average friction force, then
(f)(L) = W
(f) (1) =
(f) =
