Acceleration is the time rate of change of velocity. If velocity is constant, then. acceleration is zero. Note: 100 km per h for 10 seconds is a constant speed, but not necessarily a constant. velocity, since we're told nothing about the direction.
Many elements change how fast the car can accelerate to 60 mph. Tires, elevation above sea level, weight of the driver, equipment used for testing, and surface of testing track all play a big part in these times. Most cars are 2-seaters, although a few are family-sized. Some measurements exclude the first foot-rollout.
