A ball connect ed with string is released at an angle `45^(@)` with the vertical as shown in figure.Then the acceleration of the box at this instant will be (mass of the box is equal to mass of ball)

A uniform rod length is l hinged at A and suspended with vertical string as shown in figure it string is cut then acceleration of centre of mass at this instant will be (g = 10 m/s^2)

A simple pendulum consists of a ball of mass m connected to a string of length L . The ball is pulled aside so that the string makes an angle of 53^(@) with the verticle and is released. Find the ratio of the minumum and the tension in the string.

A ball of mass m is released from A inside a smooth wedge of mass m as shown in figure. What is the speed of the wedge when the ball reaches point B?

A ball of mass m is released from A inside a smooth wedge of mass m as shown in figure. What is the speed of the wedge when the ball reaches point B?

A ball of mass m is released from A inside a smooth wedge of mass m as shown in figure. What is the speed of the wedge when the ball reaches point B?

A mass of 0.1 kg is rotated in a vertical circle using a string of legth 20 cm. When the string makes an angle 30^(@) with the vertical, the speed of the mass is 1.5ms^(-1) . The tangential acceleration of the mass at that instant is
