Ok so i am currently taking AP Physics C. In our school there is a bit of a rivalry between the Physics C kids and the AP Chem kids. I was wondering what you guys thought about these two classes and reasons why Physics C is better (obvious bias lol).

D=Drag Coefficient p=Density of air A=Cross sectional area v=velocity a=acceleration F= force F air=(DpAv^2)/2 F net=mg-F air ma=mg-F Air a=g-(DpAv^2)/2m k=DpA/2m so a=g-kv2 dv/dt=g-kv2 dt=dv/g-kv2 using the online integrator from wolfram we got...

I appreciate you guys for looking at this but i think i got it: so basically you have two side first equation = falling pizza: x=0-1/2at^2 you set that one, equal to your thrown pizza: x=30-1/2at^2 set them equal to each other, then solve for t then use that t to solve for x

Homework Statement A pizza is being dropped from a height of 20 m. Another pizza is being thrown up at 30m/s from 0m(the one falling is above the one being thrown). At what position in the air will they meet? a= -10m/s^2 Homework Equations Im not sure but i think that some of the b5...
