I get measure the velocity numbers fairly easily with a tape measure and 
a stop watch, but I'm not sure how to effectively measure the 
acceleration, since I don't have a speedometer on the vehicle.  Can you 
approximate the acceleration if I give you (a) max speed with a rolling 
start, (b) time to go 10 feet from a standing start and (c) time to go 
20 feet with a rolling start?
