Homework Help: physics

Posted by devan on Sunday, July 6, 2008 at 8:45am.

In the below case, in dynamics, how do i solve this pulley problem using newtons laws?
here is the drawing
picasaweb,google,co,uk/devanlevin/Album/photo#5219794055569750146

what is the acceleration of each of the bodies?
the hanging body has a mass of 2kg
the lying body has a mass of 3kg

the cords and pulleys have no mass and the system has no friction.

i realise that the 2kg body needs to have half the acceleration of the 3kg, because of the manner in which it is connected to the pulley but how do i work out the exact acceleration??
