The vertical component of the rope tension equals the weight (M g) and the horizontal component equals the acceleration (M a). The ratio of horizontal to vertical components is the tangent of the tilt angle with respect to vertical.
Use those facts to solve for the acceleration, a
"M a" is the accelerating force, not the acceleration itself.
The rest of my previous answer is correct.
tan 1.0° = 0.01746 = Ma/Mg = a/g
Solve for a. g = 9.81 m/s^2
The 3.6 kg mass M does not matter. It cancels out.
