Which car is accelerating?
a) a car that is unmoving
b) a car that rounds a curve at a constant speed
c) a car that travels in straight line at a constant speed
d) a car that is set to a constant speed of 60 miles per hour

The correct answer is B) A car that rounds a curve at a constant speed.

Explanation-

Acceleration is defined as a rate of change of velocity. Hence, it is a vector quantity that is it has magnitude as well as direction.

When a car moves along a curve with constant speed, its magnitude of speed remains constant but its direction of motion keeps on changing. The change in its direction leads to an acceleration.

Thus, option B) represents that the car is accelerating.
