ok .... ohject 1 is going on a surface w.o friction. object 2 is at rest that is attached to a spring which is attached to the wall. theyll collide. its going to be perfectly inelastic and then they perform simple harmonic motion. i need to find the velocity of the first mass before the collision. so im thinkin conserv. of momentom
m1v1i + m2v2i = m1v1f + m2v2f
ok so m2v2i is 0 cz m2 is at rest. since the 2 masses combine then should the new equation be m1v1i = 2*mv
and how would i find the v in 2mv ? i know what the max speed of the oscillating masses is... would that be v?
-= Double Post =-
or is it 2m2v?
edit: no its 2mv if anything
