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 ts the radius of the curve?
The centripetal force is calculated using the following rule: F = (m * v^2) / r where F is the centripetal force = 6000 newtons m is the mass of the object = 1200 kg v is the uniform velocity of the object = 20 m/sec r is the radius of the circular curve that we want to calculate
Substitute with these givens in the above equation to get the radius as follows: 6000 = (1200 * (20)^2) / r 6000 = 480000 r r = 80 meters
