Two packing crates of masses m1 = 10.0 kg and m2 = 4.40 kg are connected by a light string that passes over a frictionless pulley as in the figure. The 4.40kg crate lies on a smooth incline of angle 41.0°.
find the acceleration of the 4.4kg crate
find the tension in the string

bobpursley,
it the incline up,or down?
Assuming the m2 is going uphill towards the pulley.
net pulling force= m1*gm2*g*sinTheta
retarding force= (m1+m2)a
set them equal, solve for a.
Tension: it is pulling against m2*g*sinTheta+m2*a
so that is what tension is.
