**Roller Coaster Physics Problem**A roller-coaster car has a mass of 511 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the diagram to point B involves only up-and-down motion (as perceived by the riders), with no lateral motion. Assume the roller-coaster tracks at points \( \mathbf{A} \) and \( \mathbf{B} \) are parts of vertical circles with radii \( r_1 = 10.0 \, \text{m} \) and \( r_2 = 15.0 \, \text{m} \), respectively.### Diagram Explanation:The diagram shows a roller coaster track with two notable points labeled \( \mathbf{A} \) and \( \mathbf{B} \). At these points, the track is part of vertical circular sections, where measurements are indicated for the radius of these circles.### Problem Statement:1. **(a)** If the vehicle has a speed of \( 20.3 \, \text{m/s} \) at point \( \mathbf{A} \), what is the force exerted by the track on the car at this point? - **Answer:** \(\text{__________ N}\)2. **(b)** What is the maximum speed the vehicle can have at \( \mathbf{B} \) and still remain on the track? - **Answer:** \(\text{__________ m/s}\)Use the given data and diagrams to solve for needed physical quantities using principles of circular motion and forces.

How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth.
