A car with a mass of 1,200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second. The centripetal force on the car is 6,000 newtons. What is the radius of the curve?

Question

A. 80 meters
B. 32 meters

C. 16 meters

D. 160 meters

Answer 1

Solve this for R:

mass x acceleration = M*V^2/R = 6000 n

Answer 2

The answer is actaully a. Radius equals mass times velocity squared divided by force. Which in this case would be 1,200 x 20(2) / 6,000 which equals 80
