Homework Statement
One fine spring day you decide to skip class and go to the amusement park to ride the loopthe-
loop roller coaster. At the bottom of the loop, you’re moving with a speed of 20 m/s in a vertical circle 20 m
in diameter. What’s the magnitude and direction of the force of the seat on you? Assume your mass is 50 kg.
Homework Equations
Vt=omega x radius
Fr=mass x omega2 x radius
The Attempt at a Solution
Vt=omega x radius
20m/s=omega x 10m
omega=10 rad/s
Fr=mass x omega2 x radius
Fr=50kg x 10rad/s x 10m
=5,000 N
I'm not sure what I'm doing at all on this problem please help me out.
I drew the FBD and the only forces are the Normal which I assume is the seats force on the rider which I further moved towards thinking that would be the Force towards the center thus the equation
Fr=mass x omega2 x radius, and the other force is (of course) g.
Please help me out I am in a bit of confusion.
Thank you for reading!
