If a ball is traveling at a constant velocity of 50 m/s for over 2 minutes, what is the ball's acceleration?
10 m/s²
0 m/s²
50 m/s²
Variable
The correct answer is: 0 m/s²
When an object is moving at a constant velocity, it means that neither its speed nor its direction is changing over time. Acceleration is defined as the rate of change of velocity over time. If the velocity remains constant, meaning there is no increase or decrease in speed, the acceleration is zero. In this case, since the ball is traveling at a constant velocity of 50 m/s for an extended period of 2 minutes, it has not experienced any change in its rate of motion. Therefore, the acceleration is indeed 0 m/s². This indicates that the forces acting on the ball are balanced, and there is no net force causing a change in its motion. Thus, the correct answer reflects the absence of acceleration in this scenario.
