one can of antioxidant (m1 = 1.0kg) on ​​the surface
of an inclined plane is connected to another can of meat (m2 =
2kg). The coefficient of friction between m1 and the inclined plane
is Uk = 0.5. Do not consider the mass of the pulley or the friction
of the same. a force of magnitude F = 6N acts upward on the meat
can, which has a downward acceleration of 5.5m / s2.

Calculate:
a) the angle assuming there is no friction on the inclined
plane.
b)the tension of the rope, when the friction acts.
