Rules:

-Collaboration between team members is encouraged,

-The authors should present the solution on a blank sheet with their names on it. Members of a team should submit together.

-Solutions should include “self-explained” diagrams/sketches, with minimal wording. Neat presentation will count toward the problem grading.

1.- Discuss an application of conservation of energy that has not been explained in class or in the textbook during the chapter or through a homework problem. Include mathematical expressions.

2.- Explain tidal waves, what make them, why they are so in different phases of the moon. Include mathematical expressions.

3.- Describe two elastic collisions and two inelastic collisions that happen in real life. In each inelastic collision explain where did the lost energy (with mathematical expressions) go, in each elastic collision explain what energy (include mathematical expressions) is conserved.
