M = 615g = 0.615kg
R = 123cm = 0.123m
V = 5.60 ms^-1
Tension = m * v / r
0.615 / 0.123 * 5.60 = 28 Nm^-1
A small object with a mass of m = 615 g is whirled at the end of a rope in a vertical circle with a radius of r = 123 cm.
When it is at the location shown, (mid-height), its speed is v = 5.60 m/s. Determine the tension in the rope.
Calculate the magnitude of the total force acting on the mass at that location.
