Explanation:
On a semicircular curve, the magnitude of force is given by the formula as :
Here, m is the mass of the vehicle
Case A : R = 60 m v = 16 m/s
Case B : R = 15 m v = 8 m/s
Case C : R = 30 m v = 4 m/s
Case D : R = 45 m v = 4 m/s
Case E : R = 30 m v = 16 m/s
The order of the magnitude of the force of the roller-coaster track on the cart from largest to smallest is :
E > A = B > C > D
