- A100 m/s2
- B200 m/s2
- C0 m/s2
- D150 m/s2
- E220 m/s2
The correct answer is 0 m/s2. When a car is traveling at a constant speed, its velocity remains unchanged over time. Acceleration is calculated as the change in velocity divided by the time taken for that change. Since there is no change in velocity, the acceleration is zero. The other options suggest positive values for acceleration, which would imply a change in velocity, contradicting the condition of constant speed.
This is not correct because a constant speed implies no change in velocity, hence zero acceleration.
This is not correct because a constant speed implies no change in velocity, hence zero acceleration.
The car is traveling at a constant speed, which means there is no change in velocity. Acceleration is defined as the change in velocity over time. Since the velocity does not change, the acceleration is zero.
This is not correct because a constant speed implies no change in velocity, hence zero acceleration.
