HW #9 -- PLEASE DO THE CORRECT SECTION!

For PHYSICS:

1) Draw a position vs. time graph showing a person walking to school, staying at school for a while, and then walking back home

2) Draw a speed vs. time graph showing a car accelerating from being stopped at a stop sign, and then a few seconds later braking and coming to a stop at another stop sign.

3) Draw the position vs. time graph for the situation in #2.

4) Draw the acceleration vs. time graph for a bowling ball pushed out of a plane at a height of 20,000 ft above the ground. Show the graph all the way to one second after the ball has hit the ground. BONUS if you can label your y-axis EXACTLY (HINT: acceleration due to gravity is a constant 10 m/s/s)

For CHEMISTRY:

Draw the complete Bohr model (with electron energy levels) for each. Then, say exactly what kind of ion the atom can form to undergo ionic bonding... (ex. -- "Na can become the positive ion Na2+"). hou can use the link to a periodic table in the HW#8 post if you need to use one and don't have yours...

1) Magnesium
2) Lithium
3) Phosphorus
4) Chlorine
5) Neon
