Problem 11E

You are testing a new amusement park roller coaster with an empty car of mass 120 kg. One part of the track is a vertical loop with radius 12.0 m. At the bottom of the loop (point A ) the car has speed 25.0 m/s, and at the top of the loop (point B) it has speed 8.0 m/s. As the car rolls from point A to point B, how much work is done by friction?

Step-by-Step Solution:

Solution 11E Step 1 of 5: In the given problem, we need to calculate the work done by friction when a roller coaster with empty car mass m= 120 kg moves from point A to point B in a vertical loop with radius r = 12 m with initial velocity at A is v = 25 m/s and final velocity at B is A vB= 8 m/s, as shown in the figure below
