Question

A car travels around a curve. What can you say about the centripetal force if the velocity is tripled?

Group of answer choices

A) Nothing - there is no information on the mass of the car.

B) Nothing - there is no information on the radius of the curve.

C) The centripetal force will increase by a factor of nine

D) The centripetal force will increase by a factor of three.

Answer 1

F = M a = M v^2 / R

If v is increased by three the force will be increased by nine,

C) is correct
