12. Explain why a roller coaster can never climb higher than its original point and why does it not matter whether one or forty people ride it.

Expert Solution

This question is all about the application of energy conservation and change of energy. now when the roller coaster is at rest it has only potential energy that is, at a higher peak position the roller coaster has only the potential energy and using this energy the roller coaster will travel the further downward path and also the following path with out using any motor. Now if the original point is lower than a point higher, the potential energy is also lower than the potential energy at the higher point. So, under this situation it not possible for the roller coaster to incrase its potential energy rather the total energy (as the total energy at a high peak point is entirely potential ). For this situation it needs a dragg by external source. It does not have anything with the mass or how much people is on it as during the entire ride the mass of the roller coaster is constant.

The situation is depicted in a diagram-

A roller-coaster track is being designed so that the roller-coaster car can safely make it around the circular vertical loop of radius R = 24.5 m on the frictionless track. The loop is immediately after the highest point in the track, which is a height h above the bottom of the loop. What is the minimum value of h for which the roller-coaster car will barely make it around the vertical loop?

A roller-coaster car speeds down a hill past point A where R1 = 11.6 m and then rolls up a hill past point B where R2 = 15.2 m, as shown below. (a) The car has a speed of 20.0 m/s at point A. if the track exerts a normal force on the car of 2.08 104 N at this point, what is the mass of the car? (b) What is the maximum speed the car can have at point...

A roller coaster car with its passengers has a mass of 220 kg and it goes through a series of horizontal and vertical curves. A. Draw the free body diagrams for the car going around a horizontal curve, the bottom of a vertical loop, and the top of a vertical loop in which the cart is upside down. Indicate the direction of the acceleration on each diagram. B. If the car is moving at 25 m/s what is the smallest...

The energetics of glycolysis can be described using a roller coaster analogy. Initial energy is invested in glycolysis through phosphorylation (and hydrolysis of ATP). This is analogous to pulling the roller coaster up the hill. If glycolysis were a roller coaster, how would you envision the rest of the ride?

A roller coaster car with its three passengers (a total of 450̅ kg) is pulled up to the top of a 30.0 meter hill where it is released at a speed of 1.00 meter per second to begin its hurtle down the track toward a 15.0 meter diameter loop the loop at the bottom. Unfortunately, the maintenance crew still has some work to do on the old rusty roller coaster track and the average frictional force on the 65.0 meter...

Centrifugal forces resulting from riding a roller coaster can be a challenge to your blood pressure,...

Centrifugal forces resulting from riding a roller coaster can be a challenge to your blood pressure, as blood trends to flow to your legs instead of your carotid arteries and aorta. A similar effect takes place as you wake up every morning. How does your body cope with these sudden changes in blood pressure?
