What two forces are combined to create the centripetal force on a cart on a roller coaster? 1-gravity and friction 2-friction and normal 3-normal and friction 4-normal and tension

The only forces acting on the rider are the upward normal force n exerted by the car and the downward force of gravity w, the rider's weight. These add together, as vectors, to provide the net force Fnet which is the centripetal force Fc, directed toward the center of the circle.

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
