Question

Two boxes (m1 = 51.0kg and m2 = 35.5kg ) are connected by a light string that passes over a light, frictionless pulley. One box rests on a frictionless ramp that rises at 30.0∘ above the horizontal (see the figure below), and the system is released from rest. Find the acceleration

Answer 1

Let T is the tension of string

Answer 2

For 35.5kg object
T-35.5*9.8=35.5*a

Answer 3

For 51kg object
51*9.8-T=51*a

Answer 4

Now add those 2 equations
a=?
