An object on a ramp is being held in place by a rope attached to the top of the ramp. If the tension in the rope is 215 N, what is the mass of the object.

We need to know the slope of the ramp, if friction is important, and if the object is on earth.
I think we have to assume friction is not important and the object is on earth.
ok
weight = m g = 9.81 m

9.81 m sin (Theta) = 215 N

where Theta is the angle of the ramp up from horizontal
ok thx
