Question

Riders on the "Great American Revolution" loop-the-loop roller coaster wear seatbelts as the roller coaster negotiates its 6.8 m -radius loop with a speed of 9.3 m/s. At the top of the loop, what is the direction of the force exerted on a 60 kg rider by the seatbelt? upward downward this force has no direction, it is (approximately) zero What would happen if the rider unbuckled at this point? the rider stays in the seat the rider falls out the rider slides horizontally in their seat at this point

Explanation / Answer

PART C:

a = v2/r -g

a = (9.32 / 6.8) – 9.81

a =2.909 m/s2

F = ma

F= 60 Kg * a

F= 174.54 N

Direction: Downward

PART D:

the rider stays in the seat

Because the seatbelt does not contribute to centripetal force
