Question

an object of mass m1= 311 g on an inclined surface. The angle of the inclined surface is θ = 40o with the horizontal. The object m1 is connected to a second object of mass m2 = 355 g on the adjacent horizontal surface. Further, an external force of magnitude ІFextІ = 3.6 N is exerted on the object of mass m1. We observe both objects to accelerate. Assuming that the surfaces and the pulley are frictionless, and the pulley and the connecting string are massless, what is the tension in the string connecting the two objects?



The pulley is at the bottom of incline

Answer 1

and is the incline up, or down? In which direction is the external force acting?

Answer 2

Incline is up. External force is pulling mass m1 over the incline, and m1 is connected to a pulley at the base of the incline which is connected to m2.
