Homework Statement
A rollercoaster car and passengers have a combined mass of 1620 kgm, and they descend the first hill at an angle of 45o to the horizontal. With what force is the roller coaster pulled down the hill?
Homework Equations
The Attempt at a Solution
Vertical force = 1620 kg * 9.81 = 15892.2 N
With a triangle in mind: cos(45) = 15892.2 / x
x[cos(45)] = 15892.2
x = 22475 N
Is this correct?
