mechanical energy problem 1

The video tutorial explains how to solve a simple dynamics problem using mechanical energy principles. It involves calculating the velocity of a coin dropped from a 100-meter building as it passes the halfway point. The instructor uses a free body diagram and energy conservation laws, assuming negligible air resistance, to derive the solution. The tutorial emphasizes understanding mechanical energy changes and solving for velocity using energy equations.

What is the value of the gravitational potential energy change during the fall?

What happens to the elastic energy of the coin during its fall?

How does the mass of the coin affect its velocity as it falls?

What is the final expression for the velocity of the coin at the halfway point?
