Apr 28, 2011 · V is used for electromotive force, eV is energy and actually means the energy gained by an electron moving through a 1 V potential difference. So you can't really convert between the two. Perhaps it would be more useful to picture V …

Feb 9, 2012 · You will have dv/dT=-kv^2. This can be solved by direct integration, after rearranging a little bit. Rearraging, this is what you would integrate, don't forget to include a constant after the integration (then solve for that constant based on initial conditions).

Jul 3, 2011 · I assume K means 10 3 so 245 rpm/kV = 0.245 rpm/V So now dividing by 1000, 0.245(10-3)krpm/V. Just invert now to get the units of V/krpm.

Aug 30, 2013 · Say we have 2 equations of progressive wave as y1=Asin(kx+ωt) and y2=Asin(kx-ωt) Where ω=kv, k=Wave Number, v=Wave velocity These equations combine according to the principle of superposition as: y1+y2=[2Asin(kx)]cos(ωt). Now we know that a standing wave is called so because all the...

Aug 1, 2011 · Since F=KV, and F=ma, by association we have ma=KV, or a=KV/m, so now we have a function of acceleration in terms of velocity. If we plug this into a=dV/dt, we end up with: KV/m = dV/dt

May 24, 2010 · Homework Statement the velocity of a skydiver falling to the ground is governed by: m dv/dt = mg - kv^2 solve for v(t) with initial conditions v(0) = 0 i rearranged equation into standard form: v' + (k/m)v^2 = g so i got an integrating factor, mu(x) = e^integ(k/m), but does the...

Sep 23, 2013 · for this problem, if it's bv i can definitely do the problem. but if it's kv 2, i don't know how to pursue the problem. for the above equation i gave, if it's kv 2, then i can put acceleration in terms of t like dv/dt. but then when i move the RHS over to the right by dividing, i cannot do the integral because i do not have an extra v term in ...

Sep 3, 2022 · Then if the object is moving up, the air resistance force should be down, i.e. negative. Moving up means v is positive, hence -kv is negative, directed down. You can work out the case where the object is moving down. It should be very intuitive, -kv means that the force is proportional to v, but has oppsitive direction as v.

Sep 29, 2007 · theres nothing else to the problem. i plugged in G-KV in for A in the first equation but now i have V=Vo+(G-KV)T. and i want to find velocity, but can't because there is velocity in the equation. so i want to know how to simplify the equation so i get V only on one side.
