Mass x Velocity prototype problem

[drewman13]

Independent non-engineer inventor is looking to determine parameters for prototype.

Compressing a piston using rolling weights.​

Need to know if a weight (wheel) is doubled in mass does that reduce the velocity loss (as a result of rolling over and compressing the piston) by one half? Assuming the initial velocity is the same for both weights.
Current prototype question:
A 10 lbs.weight (wheel) 6 inches from the axle held within a circular steel frame traveling at 7,200 rpm (282 fps = to 88,385 lbs. of centrifugal force) if that wheel ran over and compressed a perimeter-placed piston 1/4” at 366 lbs. of pressure (91 inch lbs. of total force), what would be the loss of velocity?
This is not a homework question-I am an inventor who, unfortunately, holds a communications degree.

Unfortunately, this question cannot be answered without further information. In order to calculate the velocity loss, we need to know the coefficient of friction between the wheel and the piston, as well as the frictional force and torque applied on the wheel. Without this additional information, it is impossible to determine the velocity loss.
