I'm going to read this in just a second, but since you're still up i might as ask you something else heh.
Super ball problem, and there's a step where we are supposed to:
"We can factor the momentum conversation equation out of the energy conservation equation."
Isn't that like saying...
I'm a little confused about step 3. How did you know you were supposed to integrate with repsect to time?
Here's what I understood:
We obtain the equation representing velocity, integrate and obtain position. Where at during this process do you think of taking an indefinite intergral? (I'm...
I'm having an issue getting two equations to look alike.
How can you get:
k*v + g = e^(-t*k + k*v0)
to look like:
v = -g/k + [(k*v0 + g) / k] * e^(-kt) ?
====================================
I know I can split the exponent up, and so I guess the real question is, how do I get...
Yeah, in order for the units to match up i believe k would technically need to have units of 1/t.
And yes, a is dv/dt. So instead of writing:
a = ..., I've substituted dv/dt = ...
This way, we can say dv = blah (partial derivative dt)
Integrating both sides, we then obtain the velocity equation.
Sunday night physics problems :(
Alright, so I'm supposed to find the displacement equation for a particle fired vertically under a constant gravitational field, where the resisting force is proportional to the instantaneous velocity of the particle. Here's where I'm at:
Fup = ma; Fdown =...
