AI Thread Summary
The discussion revolves around finding the launch angle based on a series of given velocities at different time intervals. The initial velocity at t=0 is v=2i + 4j, which indicates the launch velocity. A participant expresses confusion about calculating the launch angle from these vectors. The conversation highlights the importance of understanding vector components in physics. Overall, the thread emphasizes the need for clarity in vector analysis for accurate problem-solving.

I'm having troubling finding a launch angel from a set of given velocities.

v=2\hat{i}, 4\hat{j} at t=0

v=2\hat{i}, 2\hat{j} at t=1

v=2\hat{i} at t=2

v=2\hat{i}, -2\hat{j} at t=3

the g=-2 on this planet

angel? o:)
v=2\hat{i}, 4\hat{j} at t=0

doesn't this line tell you the launch velocity? :wink:
 
Thanks for the welcome!

got it, I'm still a bit shaky with vectors.

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Do electron density waves accompany EM waves in coaxial cables?'

Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
