At the top of the hill
Fn = mv^2 / r - mg
= 1780 * ( 17.9^2 / 15 - 9.8)
= 20578 N
so the force of the track on the car is 20578 N

A roller-coaster car has a mass of 498 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and- down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points and Bare parts of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of...
