Question 160953: a 20 kg is pulled on a horizontal frictionless surface by a rope that makes an angle of 37 degree with the horizontal. Calculate the tension in the rope if the block accelerates at 2m/s2.

There is no frictional force acting on the block but there is a component of gravity acting against the block.
The force balance, parallel to the slope, would be

where T is the tension of the rope and is the angle of incline,

The tension on the rope is 158 N.
