    BY GOD I THINK I FIGURED IT OUT. thank you so much!

    Scratch that. (1585-200+30) m/s?!

    (1585 - 30 + 200) m/s?

    Object In Orbit pushed by a velocity and crashes onto moon.

    I found that the initial velocity of the LEM is 1585 m/s from the first problem. I do not understand how to incorporate the 200 m/s cast away speed into the problem. I've tried every combination of numbers into the angular momentum and energy conservation formulas but no luck. I'm desperate and...

    Object In Orbit pushed by a velocity and crashes onto moon.

    I changed 200 m/s to 1704 m/s as that is the speed of the LEM at engine shut off. It's still wrong. Does the LEM gain speed as it travels closer to point B?

    Homework Statement I attached the problem to this post. I need help on the second question and I need to turn it in tomorrow. I'm not sure if I'm supposed to use anything from the first as they are both related. Homework Equations U + KE rvsinθ = rvsinθ These are all the equations...

    Mass on wedge on incline problem

    Homework Statement The problem is provided in the pdf attachment Homework Equations I know how to solve frictionless problems with a single mass on an incline but this is just too advanced for me. (especially with two inclines of different angles) The Attempt at a Solution I drew...
