Hello, Can you help me with the following questions, please

1. Define Linear Momentum. Explain the relationship between linear momentum and Newton's second law?

2. Differentiate between Elastic and Inelastic collisions with examples.

3. (a) What is the momentum of a garbage truck that is 1.20 x 104 kg and is moving at 15.0 m/s? (b) At what speed would a 6.00-kg trash can have the same momentum as the truck?

4. The child bounces in a harness suspended from a door frame by a spring constant. (a) If the spring stretches 0.300 m while supporting an 10.0-kg child, what is its spring constant? (b) What is the time for one complete bounce of this child?

5. Explain Archimedes Principle with example? When can we say that the object is floating or sinking?
