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...
