A car going around a certain curve at a speed of 25 km/h has centripetal force of 100 N acting on it. If the speed of the car is doubled, the centripetal force:
Correct answer: A. Is quadrupled
- A. Is quadrupled
- B. Is doubled
- C. Is multiplied by √2
- D. Is reduced to 1/2 of the original value
- E. Is reduced to 1/6 of the original value
Explanation
The formula that will be used here will be: F=(m)(v)2/r. By doubling the speed of the car, the centripetal force should be quadrupled due to the power of 2.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
