it was just a round about way to get the mass of the planet, escape velocity didn't need to be mentioned. All the tools were there. I just forgot the direct way to get to the mass. As for m2, that is the mass of the planet, m1 cancels out. m2 didn't cancel out, therefore it was still part of...

Homework Statement You are a space traveler and you land on the surface of a new planet. You decide to drill a tunnel through the center of the planet to the opposite side of the planet. Your idea is to use this tunnel to easily transport rocks from your location to the opposite side of the...

alright thanks, I almost got it now

So there will be a bigger force acting upon q as opposed to 2q. The angle between the vertical and q will be bigger than the other. I guess I am having trouble relating that into the formula, or even figuring out how to get the angles out of it. I am sorry for the huge mind block that I am...

Homework Statement A textbook of mass m = 1.24 kg starts at rest on a frictionless inclined plane (angle  = 30◦). Although there is no friction, suppose there is a drag force (due to air resistance) acting on the book which is proportional to the speed squared and is described by the...

E&M Problem -- 2 Charged Masses Hanging on Strings Homework Statement Two charges of identical mass m, one with charge q, the other with charge 2q, hang from strings of length l from a common point. Assume q is sufficiently weak so that any angle you're looking for is very small, and find...

Thanks guys! I solved it now! The help really worked, I just needed to write those equations and visualize the constraints so I could maximize properly

Actually idk if that will work. velocity in the x direction and y direction are still unknown, so that's to many variables and not enough equations. I could turn Vx into V*cos(theata). But I still have to many unknowns. I feel like there might be another way at going about this.

CAF123, I will try that and see where I get. As to Zondrina and abrewmaster, thanks for the help but not sure those methods will work. Even though an angle is given in the problem, that was for previous parts not listed. For this one I need to find the maximum velocity and the angle that...

Homework Statement A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.73 m directly above the back line, and the ball's initial velocity makes an angle theta = 40 degrees with respect to the...

nmv I got it Thanks!

I guess I am not too sure of what that means.

Homework Statement You will recall from our discussion of the Franck-Hertz experiment that the energy difference between the first excited state of mercury and the ground state is 4.86 eV. If a sample of mercury vaporized in a flame contains 1.02×10^20 atoms in thermal equilibrium at 1613 K...

solved it myself, if anyone needs help doing semi finite plates with steady temp, let me know

nvm I solved it myself, anyone interested in learning how to solve the heat equation for semi finite plates with steady temp let me know
