Homework Statement Two identical masses m are initially at rest, separated by a distance x. A constant force F accelerates one particle until it collides and combines with the other. What is the mass of the resulting particle? Homework Equations F = gamma3mv The Attempt at a...

Hmm could you possibly explain what race mates are? And yes this is very likely; those two are on topic with what we have recently learned... I keep chuggin at it

I would do that, but I'm not good enough at it yet where I can see ten steps in reverse =/. Okay I don't even know if I'm beginning right, but let's say we add Et2CuLi with an H+ workup to the one on the left to get the ethyl on the bottom... I'm not quite sure how to swap out the oxygen w/...

I can't imagine that would be the final step... We definitely have not used that in any of our synthesis problems yet, and I looked it up and I can't see how ozonolysis could lead to that... Did you see that it goes Desired product --> Starting materials?

Homework Statement http://i.imgur.com/H8p56.jpg 2. The attempt at a solution I'm not quite sure how to start this one... I would assume organolithiation could get me started for the two combining, but I'm not quite sure how to get the 3' carbon to spout that ehtyl group or how to...

Homework Statement http://isites.harvard.edu/fs/docs/icb.topic725237.files/problemset3_2010.pdf (Problem 1) Homework Equations f=ma, string conservation The Attempt at a Solution I'm not really sure how to do this. I know that the t of the string on the left is equal to the two...

Homework Statement http://imgur.com/a2fLm Homework Equations F = ma is it The Attempt at a Solution The problem I had is that it's attached to the floor all of a sudden. Never before have we had Atwood problems like this, and I can't find any online... I drew out the free body...

Sigh that's so easy... I wish I had a textbook ;( thank you

I was being a little silly on the gravity pull part :/ I was thinking in terms of acceleration not in terms of Force (which obv. would have m =/ ). I just haven't done this in so long things are coming back to me.

Trying to figure it out =/ that's about as far as I originally made it. You know the force on the system has to be ma, so since mass is (m+M), the acceleration of the system is a = F/(m+M). Now I assume since the acceleration is moving forward, the block on top of the wedge would have to move...

Homework Statement A wedge with mass M rests on a frictionless horizontal tabletop. A block with mass m is placed on the wedge and a horizontal force F is applied to the wedge. What must the magnitude of F be if the block is to remain at a constant height above the tabletop? Homework...
