(b)
The velocity of the circular motion will be tangential at each location. According to Newton’s first rule of motion, if the rope snaps suddenly, the stone will move in a tangential path.
If in problem 21, the speed of the stone is increased beyond the maximum permissible value, and the string breaks suddenly, which of the following correctly describes the trajectory of the stone after the string breaks: (a) the stone moves radially outwards, (b) the stone flies off tangentially from the instant the string breaks, (c) the stoneflies off at an angle with the tangent whose magnitude depends on the speed of the particle?
