1) A 50 kg block rests on a horizontal surface. The coefficient of static friction is 0.50. The coefficient of kinetic friction is 0.35. A force P of 250 N is applied as shown:

[]--------->P

First, can we make conclusions given the data? If not, why not? If so, does the block move and continue to move at a constant velocity?

2) A block is placed on a plane whose angle of inclination is 30 degrees. THe coefficients of static and kinetic friction for the block on the inclined plane are both 0.2. The block........

In this case, would the block accelerate down the plane? If not, what does the block do?

3) Two objects are sliding at the same speed across a wooden surface. The coefficient of kinetic friction between the first object and the surface is twice that between the second object and the surface. The distance traveled by the first object before it stops is S. The distance traveled by the second object is:

Would the answer to this be S/2? Why or why not

TRUE or FALSE:

1. The production of methane gas occours very rarely in nature.

2. Gas formation is a phase not a chemical change.

3. Every chemical reaction involves energy in some form.

4. Every chemical bond does contain energy.

5. Chemical reactions are studied by the energy contained in the productsin comparison to the reactants.

6. Chemical changes must involve the breaking and making of chemical bonds.
