m3 = mass of satalite (G m3 m2)/x^2 = (G m3 m1)/(3.84 E 8 m - x)^2 I can cancel out the m3 and the G right?
ok I'll be using a home work problem to ask the question. I'm not asking for help on the question I got the correct answer just need to understand this concept better. Calculate the acceelration due to gravity on the Moon. The moon's radius is about 1.74 E 6 meters...
ok i get it see new question
Fg exerted by whatever it's orbiting onto moon = r^-2 G (mass of moon) M = to the gravitional force exerted by moon onto M = Mg ok then you can divide by M but why is it the force of gravity exerted by the moon onto whatever it's orbiting mass M just equal to Mg ??? Pl...
ok net force = m a only force present force of gravity Fg = mg = r^-2 G m M were m is the mass of the moon and the M is the mass of what ever it's orbiting... correct? Fg = mg = r^-2 G m M divide both sides by the mass of the moon g = r^-2 G M so I guess I just don't g...
Us = (rg)^-1 V^2 Us = (.12 m (9.80 kg^-1 N))^-1 (22.35 s^-1 m)^2 Us = 420 back of book says .34
50 mph is in the question in the book
very easy algebra one
which expression is correct from this 180 s(a t3) THIS ONE??? (180 s)a + (180 s)t3 or this ONE??? 180 s * a * t3
I just need to know how to start this equation because it makes no sense The position of a particle is given by r = (6.0 cos 3.0 t i + 6.0 sin 3.0 t j) meters. Determine (a) the velocity vector, v, and (b) teh acceleartion vector, a. (c) What is the parth of this particle? [Hi...
Physics (Algebra Bit)
Is the answer to (c) correct by the way for the other problem I didn't know how fast it would be accelerating realtive to the larger block because teh larger block would be accelerating more at 5.2 s^-1 m and the smaller block accelerates at 3.2 s^-1 m so I wasn't sure...
