A ball is attached to a string that is attached to a pole. When the ball is hit, the string wraps around the pole and the ball spirals inwards sliding on the frictionless surface. Neglecting air resistance,what happends as the ball swings around the pole?

A ball attached to a string length L is oscillating line a simple pendulum. Find v in terms of v_0 L alpha and beta .

Figure below shows a small mass connected to a string, which is attached to a vertical post. If the ball is released when the string is horizontal as shown, the magnitude of the total acceleration (including radial and tangential) of the mass as a function of the angle Theta is

Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

A ball of mass 200g is attached to a string of length 50cm and a force F is applied on it as shown. Find the work done by this force if string makes an angle 60^@ with vertical. In the initial and final position, speed of the ball is zero.
