A 800 kg car is turning round a corner at 6 m/sec as it travels along an arc of circle of radius 12 m. The magnitude of force exerted by pavement on the tyres to hold the car in circular path is _.
Correct answer: A. 2400 N
- A. 2400 N
- B. 1200 N
- C. 400 N
- D. 4800 N
Explanation
The formula for the centripetal force will be used here, which is: F=mv2/r Where m is the mass, v is the velocity and r is the radius. F=(800)(6)2/12 Solve the right-hand side of the equation to obtain: F=2400N

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.
