1. Two particles of equal mass are orbiting each other in circular orbits. What is the radius at which they orbit?
Energy = T + U = 0 (for circular orbits)
T = 1/2 m v^2
U = -(Gm*m)/r + [L^2] / [2(mu)r^2]
period=[2 pi r] / vt
vt is tangential velocity
L is angular momentum...
Nevermind! The problem is solved. For future reference, you merely take the derivative of the L equation with respect to alpha. Do a few trig identities in order to get one alpha in the equation and solve.
Rifleman's Rule: Best angle for a projectile up a hill [urgent]
Homework Statement
A projectile is fired at speed Vo at an elevation angle alpha up a hill of slope beta (alpha>beta). At what angle will the range (L) be maximum?
Homework Equations...
R, according to your words, is the projectile's distance over a flat surface. I am trying to find the angle of maximum projection up a slope as a function of AC and theta.
I understand how to find R, but I'm not trying to find that. I am attempting to find the angle at which the projectile will land the farthest up the hill for a given Vo.
My thoughts are that we make beta = 0 and alpha = 45, but I believe the professor is looking for an equation instead of an actual number so that I can prove it is the best angle.
How do you find the maximum range a projectile will hit (shot at angle alpha) on a slope (angle theta) when theta is less than alpha. Also, what is the best angle for alpha. I would only like a head start, do not post the answer please.
We know that there are constants alpha, theta, and Vo...
Sorry for the wait boys and girls, I went home and had a bit of trouble setting up the dial-up. Anyways, as soon as I get back to school, I will get you some pictures. Unfortunately, my lab partner is probably not around since she goes home on the weekends and I don't believe my advisor is in...
If it were a strobe effect it would affect the entire picture each time it happens, but unfortunately this is not the case. They are vertical lines that scroll across the screen.
From what I am seeing, Pockel cells are the vibrating object that we would put in front of the laser. Our goal is to be able to study many different kinds of things, not just pockel cells. But I really don't know what one of those are anyways, lol.
