Example

Problem: You are testing a new amusement park roller coaster with an empty car with a mass of 120 kg. One part of the track is a vertical loop with a radius of 12.0 m. At the bottom of the loop (point A) the car has a speed of 25.0 m/s and at the top of the loop (point B) it has speed of 8.00 m/s. You may want to review (Pages 203 - 212).For related problemsolving tips and strategies, you may want to view a Video Tutor Solution of A vertical circle with friction. As the car rolls from point A to point B, how much work is done by friction?
