Two objects are connected by a light string that passes over a frictionless pulley as in the fi gure. One object lies on a frictionless, smooth incline. In the figure, m1 = 8.48 kg, m2 = 4.84 kg, and  theta = 40.2 degrees . When we let go of the mass m1, it accelerates downward, pulling the mass m2 up the incline. Find (a) the magnitude of the acceleration of the objects and (b) the tension in the string.

1. write the net force equation, clockwise is positive.
Net force= total mass* a
M1*g-M2*g*sinTheta=(M1+M2)a
find a.

Tension: just above M2

m1(g-a)=T
