A conical pendulum is set up with a bob whose mass is 6.0 kg. When it is set in motion, at a speed of 0.60 m/s, the string makes a 12.0 degree angle with the vertical. a) Find the radius of the horizontal circle the conical pendulum traces out. b) Find the length of the string.c) Find the magnitude of the tension in the string.
A string can support a stationary hanging load of mass 25 kg before breaking. a) Calculate the maximum tension that the string can support. b) Suppose one end of the string is attached to an object of mass m = 3 kg, while the other end is fixed to the center of a frictionless table as shown in the figure. When given an initial speed, the object moves along a horizontal circle of radius R = 0.8 m. Calculate the maximum speed the object can have before the string breaks.
