URGENT EXAM
A roller coaster with a car of 1000kg travels at 20.8 m/s in point A, when it enters to a verticsl loop of radius 3.99m. ignoring losses, calculate the magnitude of the normal force that the rollercoaster projects to the car in point B in top of the loop. result in kN. URGENT EXAM

Answer #1

using conservation of energy

total energy at A = total energy at B

0.5 m Va^2 = mg ( 2R) + 0.5 m Vb^2

(2 x 3.99) + (0.5 x v^2) = 0.5 x 20.8^2

v = 20.413 m/s
