Just to be clear, I am putting the maximum acceleration in for a. Also, I have made the assumption that the stopping distance (s) is small compared to the jumping height.

Called Distronic, it also operates at high speed and adjusts both braking and acceleration to maintain a constant distance from other cars. If a collision seems likely a warning is given.

Since quick acceleration over a short distance is the key to winning a short race, Piazza says the trade-off makes sense for sprinters.
