Part A
Complete these steps for each material listed in the table. Record your findings in the table.
1. Describe the appearance of the material. Include its color and state (solid or liquid).
2. Pour 14 cup of water into a small, clear container. Measure 14 teaspoon of the material, and carefully
pour it into the container. Look at the side of the container as you pour in the material. Decide
whether the material is less dense or more dense than water by observing whether the material
floats or sinks.
3. Swirl the container to see whether the material mixes with the water.
4. Rinse and dry the container and the measuring spoon after each use.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
