An object moves at a constant speed along a curved path. at the point where the path curves most sharply, the object has the highest acceleration highest velocity lowest acceleration lowest velocity

  Highest acceleration

Step-by-step explanation:

Acceleration is the rate of change of velocity. When the speed is constant, the velocity will be changing at a higher rate if its direction is changing at a higher rate. Where the curve is the sharpest, the direction change is the fastest, so that is where there is the highest acceleration.
