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.
equal and opposite force which pushes the car forwards. The tyres must have good grip (a high friction) so that they do not slide on the road surface. If the forces of thrust and drag are equal, then the forces are balanced and the car will move with a constant velocity. If the forces of thrust and drag are not equal, then the forces are unbalanced and the car will accelerate. The car will get faster if thrust is bigger than drag, and slower if the drag is bigger than the thrust. Links Forces and Motion Force Revision Questions
