# A bob of mass m is moving in a vertical circle

An object of mass 3.0 kg is whirled around in a vertical circle of radius 1.3 m with a constant velocity of 6.0 m/s. Calculate the maximum and minimum tension in the string. Consider a small body of mass 'm' attached to one end of a string and whirled in a vertical circle of radius 'r'. In this case, the acceleration of the body increases as it goes down the vertical circle and decreases when goes up the vertical circle. Hence the speed of the body changes continuously.

The mass on the bottom would still be m 'cause that's the mass of the yo-yo going in a circle. But instead of T plus mg, we'd have T minus mg since gravity's pointing radially out of the center of the circle. Swinging a mass on a string requires string tension, and the mass will travel off in a tangential straight line if the string breaks. The centripetal acceleration can be derived for the case of circular motion since the curved path at any point can be extended to a circle.
