Question

A roller coaster is entering a vertical loop which has a radius of 25.0 m. If the coaster is

traveling at 45.0 m/s as it enters the loop, how much is the centripetal force that you
experience? (Assume your mass to be 75.0 kg and the velocity to be constant.)

Answer 1

6080 N

Step-by-step explanation:

F = m v² / r

F = (75.0 kg) (45.0 m/s)² / (25.0 m)

F = 6075 N

Rounded to three significant figures, the centripetal force is 6080 N.
