    Block on movable wedge pulley system

    If to displace the wedge by lets say x meters then the string which you marked with green will displace x similarly the blue one would move x too hence total disp in x dir would be equal = 2x this would result in the increase of length in the red string as the string is inextensible..... what...

    Rotational: angular momentum

    Homework Statement a spool of radius R1 and R2 (R2>R1) is kept on hortizontal surface. A force f= 2t N (where t is time ) acts on the inner radius tagentially find the angular momentum of the system about the bottomost point of the spool. Homework Equations v=u+at W=Wi+alpha(t) L=IW+mvr...
