Jared sits in the chair with his legs sticking straight out. Carmen sits in the chair cross-legged. Which team is most likely to win? Explain your reasoning.
Expert Solution
Step 1

carmen wins the match.

This can be explained by considering Newton's first law of motion, conservation of angular momentum and the concept of moment of inertia.

Newton's first law of motion : also called a as the Law of inertia states that an object in motion will stay in motion until an external force acts o it. 

      conservation of angular momentum is the corresponding principle that applies to rotating or spinning objects. Angular momentum is the product of angular velocity and moment of inertia.

Moment of inertia is defined as the product of mass of the object and distance between each particle from the reference axis.
