Mass and cord tension of mass on a frictionless plane
Not what you're looking for?
A block with unknown mass M is held stationary on a frictionless plane inclined at angle b= 30 degrees, by a cord attached to the ceiling. The angle between cord and ceiling is angle a=50 degrees. The normal force exerted on the block by the plane is N= 74 nt. SEE ATTACHMENT #1 for arrangement.
Part a. On the diaqram shown as ATTACHMENT #1, show as arrows, all forces acting on the block.
Part b. Find M, the mass of the block, and T, the tension force in the cord.

Solution Summary
The expert examines the mass and cord tension of mass on a frictionless plane.
Solution Preview
Part a.
SEE ATTACHMENT #2 for all acting forces and x,y system with x parallel to the plane.
Part b. Step 1.
For stationary objects, 'net force = 0' holds for both x and y directions. Thus we can write that; (1) 'total +x forces must equal total -x forces'. Note the angles ...
