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.
It maintains a constant speed, but not a constant velocity because its direction is changing when it rounds the corner 6. Acceleration = change in v/t = 100 km/h/10 s = 10 km/h.s. 7. Zero, because there is no change. People get this wrong because they fail to see that a constant 100 km/h is not a change of 100 km/h. 8.
