8) A roller-coaster car has a mass of 1780 kg when fully loaded with passengers. The car passes over a hill of radius 15 m, as shown. At the top of the hill, the car has a speed of 17.9 m/s. What is the force of the track on the car at the top of the hill? 15 m

Answers

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
