On Roller Coaster ;-) ;-)

Classical Mechanics Level 4

A roller-coaster vehicle has a mass of 500 kg when fully loaded with passengers, If the vehicle has a speed of 20.0 m/s at point A then what is the force (in Newtons) of the track on the vehicle at this point?

Take acceleration due to gravity as 10 m / s 2 m / s^2 .


The answer is 25.

nice one ...correct ans is 25... mv^2/r+mg=n....hahahaha....

Shouldn't the ans be 20kN because radius of curvature is given to be 10m and normal reaction would provide necessary cp force, which is equal to mv^2/r.Solving, we get 20
