Question

An object of mass 0.91 kg is being revolved in a vertical circle of radius 6.5m with uniform speed of 14. m/s by means of a rigi metal rod. Determine the tension in the rod, by the time the object is at a point whose position vector is directed 10deg south of west.

Answer 1

The tension in the rod is simply the force required to accelerate the object.
If we use Newton's Law
\[F=m*a\]
\[F=m*v^2/r\]
We know m, v, and r
Now let us examine a free body diagram to solve for the forces
