A 0.5 KG mass attached to the end of a string swings in a vertical circle of radius 2 m. When the mass is at the lowest point of a circle, the speed of the mass is 12 m/s. The magnitude of the force in (N) of the string on the mass at this position is approximately?
Homework Answers
given that
mass m = 0.5 kg
radius r = 2 m
speed at the lowest point v = 12 m/s
from the free body diagram
F-mg = Fc = mv^2/r
F = mg+mv^2/r
F = 0.5*9.8+0.5*12^2/2
F = 4.9+36
F = 40.9 N
