Question

A car rounds a curve while maintaining constant speed. Which of the statements is correct?

a. The acceleration of the car is zero
b. No net force acts on the car
c. The velocity of the car is zero
d. The velocity of the car is constant
e. A net force acts upon the car

Answer 1

When a car rounds a curve while maintaining a constant speed, it is accelerating because its velocity is changing even though its speed stays constant.

Step-by-step explanation:

b. When a car rounds a curve while maintaining a constant speed, it is accelerating. Acceleration is defined as any change in velocity, which includes changes in speed or direction. In this case, the direction of the car's velocity is changing because it is moving around a curve. Although the car's speed may remain constant, its velocity is changing, which means it is accelerating.
