Okay, well if you take 4/10 you get like 0.4 hz then.
Since you know the velocity = 12 m/s and you know the frequency then you can find the wavelength. The only thing is , you get an answer of like 30 m. If you look at that graph I find that almost impossible to correspond.

I've been trying out things on this problem, I really need some help. I tried finding the frequency by counting the waves and dividing it by the seconds it takes through the waves. EX : 4 (Waves)/...

So I am doing this roller coaster lab in my physics class and I'm having some problems.
You have to find the initial height of a hill and initial velocity; which was easy and I found this out.
PEi = PEf+KEf
m*9.8*h i = m*9.8*0.4572 + 1/2*m*(1.5m/s)^2
m's cancel

If the space station orbits the Earth 225 km above the surface , what are the satellites orbital speed and period ? The mass of the Earth is 5.97 E24 kg and the radius is 6.38 E6 m.

The Attempt at a Solution
I already have the speed ( v ) , I...
Okay I got the answer, but I don't think it's as long as I calculated. I got something like
2.05*10^25
I can see it being 2 years, but what am I doing wrong?
That the period of orbital is squared and that radius is squared, and this proportional between two planets , I believe ?
So it would actually work with distances and period orbitals of other planets correct ?
Homework Statement
An asteroid is located between Mars and Jupiter. It is thought that a planet once orbited here but was somehow destroyed and broken up into small chunks(perhaps by getting hit by a comet or asteroid). If an asteroid in this belt has an average distance from the sun of 500 *...
Taking the Mass B * G = A(Mass B + Mass A)Mass B = 10g = 0.01 kg
Mass A = 500G = 0.5 kg
0.01*9.8 = A ( 0.01 + 0.5)
0.098 = A 0.51
A = 0.19 m/s^2
Vf^2 = Vi^2 + 2 ad
Vf^2 = o^2 + 2 0.19(1.50)
Vf = 0.76
Then use this formula
Vf = Vi + a T
0.76= 0+ 0.19(t)
T= 4 seconds
For Mass A aka 500G
the equation what setup like this :
Ft=MassA * a
(Orginally Ft-Ff=MassA * a ; til I knew to just forget friction)
Mass B was set up like so :
Mass B * G - Ft =Mass B * a
Substituting Mass A for Ft : Mass B * G - Mass A * a = Mass B * a
