Homework Statement
The diagram shows a block and pulley
system where all the surfaces are
frictionless, and all the pulleys are
massless and frictionless.
Express the magnitude of the acceleration of Block 2, a2, in terms of a1 and/or a3.
Homework Equations
F=ma
The Attempt at a Solution
FBD for block 1
m1 * a1 = T
a1 = T
fbd for block2
m2 * a2 = 2T - m2*g
a2 = [2(a1) -m2*g]/m2
a2 = a1 - g
But i am wrong for some reason..
It looks like the answer is a2=3/2 * a3 or 3/4*a1
Any help would be awesome
