As a car speeds up when rounding a curve, does centripetal acceleration also increase? Use an equation to defend your answer.
Whether the centripetal acceleration also increases when a car speeds up when rounding a curve.
Answer to Problem 44A
Yes
Explanation of Solution
Introduction:
When an object moves around a circle of radius
Using the above formula, if the radius is constant, then
Now, when a car speeds up when rounding a curve, then because of the radius of the curve being constant, the centripetal acceleration increases with the increase in the speed.
Conclusion:
Hence, the increase in the speed of the car along the curve results in the increase of the centripetal acceleration.
