    Harmonics Question; prove that v max of a mass on a spring is given by 2 pi f A

    But if we want an answer without straying from the text (assuming you are using ILC's SPH4U funded by TVO), then we can go to Lesson 6, page 12. Right at the top, it gives the equation T=2(pi)r/v *If you know how to graph trig functions, or understand them even in the least, you know that the...

    Gravity: Point where Earth's Gravity and the Moon's cancel each other out?

    I believe I have finally found the answer. E= *10^ 1. 5.98E24/r^2 = 7.35E22/ (3.84E8)^2 - r^2 2. 5.98E24/r^2 = 7.35E22/1.47E17 - r^2 3. 5.98E24*1.47E17-5.98E24r^2=7.35r^2 4. 8.79E41= (7.35E22+5.98E24)r^2 5. 8.79E41= 6.05E24r^2 6 √(8.79E41/6.05E24) = r The answer then suggests the point...

    I am working on the same problem. I had got as far as berkeman's post. However, I cannot seem to go any further without coming to an unreasonable answer. Can anyone provide any more help please?
