Example

Problem: A 350 kg roller coaster starts from rest at point exttip{A}{A} and slides down the frictionless loop-the-loop shown in the accompanying figure.A. How fast is this roller coaster moving at point B exttip{B}{B}?B. How hard does it press against the track at point Bexttip{B}{B}?

FREE Expert Solution

We'll use the law of conservation of energy:

Ki+Ui+Wnc=Kf+Uf, where Wnc is the work done by non-conservative forces such as friction.

Potential energy:

U=mgh

Kinetic energy:

K=12mv2

A.

In this problem, we don't have no-conservative forces, and hence Wnc = 0.
