... I use a power chair because I have acute congestive heart failure (I can't breath). So my experiment today was: at a rate of 61 mph on damp pavement what is the maximum BOUNCE height and distance of travel will a standard power chair make?

ANSWER: At sea level with a barometric pressure of 29.8, if the chair is correctly sheared from the back of the vehicle using strong impact force, it will bounce approximately 12.3 feet 4 times- each time the bounce gets progressively shorter. Once the bounce ceases it will slide another 41 yards.
