Q1) The formula for the Conservation of Momentum for a collision between two objects is:

where m1 and m2 are the masses of the two objects, respectively, u1 and u2 are their initial velocities before collision, and v1 and v2 are their velocities after collision. Using this formula, answer the following question:

1. For all the tests above, the masses of the balls are equal. With test #1, if the initial velocity (u1) of the first ball is 5 m/s, use the formula to mathematically prove Conservation of momentum (hint: show that u1 = v2).

Q2) Collision balls of different masses and materials

1. Take two balls made of two different materials with noticeably different masses.Now make these two balls collide with each other. How does this collision differ from those observed in the previous experiments above?

Q3) What would be a real-world application or scenario in which the concept of Conservation of Momentum and Energy and its formulas would be used?
