Question

5. Consider a roller coaster ride, as shown below. The passenger car starts from rest at a height of 50.0 m, gliding down a frictionless track, entering a vertical circular loop with a radius of 10.0 m ($g = 9.8 \text{ m/s}^2$). Find: (a) The speeds of the car at the bottom and top of the loop. (5 points) (b) The centripetal accelerations of the car at the bottom and top of the loop. (5 points) (c) The forces between the passenger body (with a mass of 100 kg) and the seat at the bottom and top of the loop. (10 points)

Step 1

At the bottom of the loop, the car is at its lowest point and has the maximum speed. To find this speed, we can use the principle of conservation of energy. The initial potential energy at the top of the loop is converted into kinetic energy at the bottom of the Show more…
