Hrmm...I can't quite think of how to use that at the moment, but I did remember about the equation for displacement in SHM: x=A\cos \left( \omega\,t+\phi \right) And the first derivative of this equation gets me: -A\sin \left( \omega\,t+\phi \right) \omega The problem is I can't seem to...

Homework Statement While visiting friends at Cal State Chico, you pay a visit to the Crazy Horse Saloon. This fine establishment features a 200- kg mechanical bucking bull that has a mechanism that makes it move vertically in simple harmonic motion. Whether the “bull” has a rider or not, it...

D'oh! Tyvm.

Alright, then here is what I got from davieddy's help: K + U = K + U MC = mass of the comet MS = mass of the sun G = gravitational constant So...here is my equation, followed by the steps to make it solve for V2: .5 * MC * V1 ^ 2 - G * MS * MC / D1 = .5 * MC * V2 ^ 2 - G * MS *...

O.K...so since the times and areas are equal, we can safely set both sides to equal the area of a triangle? i.e. .5 * R1 * V1 = .5 * R2 * V2 thus, V2 = V1 * R1 / R2 But then I get 9.72E4.

Homework Statement Comets travel around the sun in elliptical orbits with large eccentricities. Suppose the comet has an initial speed of 1.17*10^4 m/s when at a distance of 4.9*10^11 m from the center of the sun, what is its speed when at a distance of 5.9*10^10 m? Give your in m/s in...
