This is a simple conservation of momentum problem, so assume that at the beginning, total momentum is equal to 0 Afterwards, the total momentum must stay the same. Thus: Momentum(before) = Momentum(boy) + Momentum(jug) This should be enough to get you started

Nevermind, figured the problem out.

Homework Statement A pendulum constructed of a solid sphere, bar, and block, each with mass m=4 kg The sphere has radius R, The bar attaches the block and sphere and has length 2R, and the block has a center of mass R away from the end of the bar. The axis of rotation is halfway between the...

Thanks :) It's been years since I've had to look at a graph like this...

Homework Statement Given this graph: [PLAIN]http://img683.imageshack.us/img683/2403/xvtt.jpg where is x>0, x<0, x=0, v>0, v<0, v=0, a>0, a<0, a=0? The Attempt at a Solution I figured out everything up to the accelerations, it's just been a long time since I've had to do a problem...
