Also I couldn't find the...
Homework Statement
A comet passes the sun at it's perihelion 5*1010 meters going 1*105 meters/second. Take the mass of the sun to be 2*1030.
a.) Will the comet return to this point? If so, how long until that happens?
b.) How long will it take to travel from perihelion to 60 degrees...
Ahahaha! I got it. Man, physics/math at it's finest. Thanks, those last two sentences really helped me out. Once I figured out how to get rid of the sine/cosine terms in the conservation of energy terms, it was a piece of cake.
Homework Statement
A block of mass M is connected to a spring of mass m and oscillates in simple harmonic motion on a horizontal, frictionless track (Figure P15.62). The force constant of the spring is k and the equilibrium length is l. Assume that all portions of the spring oscillate in...
Oh man...
As a word of advice for anyone who needs this advice.
ALWAYS ALWAYS ALWAYS... Check to make sure your calculator is in (degrees/radians) before you spend an hour staring at your work, an hour looking for help in real life, an hour looking for help on the internet, and an hour...
