A rod of length 50cm is pivoted at one end. It is raised such that if makes an angle of `30^(@)` from the horizontal as shown and released from rest. Its angular speed when it passes through the horizontal (in rad`s^(-1)`) will be (`g=10ms^(-2)`)

One end of a straight uniform 1m long bar is pivoted on horizontal table. It is released from the rest when it makes an angle 30^(@) from the horizontal (see figure). Its angular speed when it hits the table is given as sqrt(n)s^(-1) , where n is an integer. The value of n is ..............

A rigid rod of mass m & length l is pivoted at one of its ends. If it is released from its horizontal position, find the speed of the centre of mass of the rod when it becomes vertical.

A rigid rod of mass m & length l is pivoted at one of its ends. If it is released from its horizontal position, find the speed of the centre of mass of the rod when it becomes vertical.

A body is projected at an angle of 30^(@) with the horizontal and with a speed of 30ms^(-1) . What is the angle with the horizontal after 1.5 second? (g=10ms^(-2))

A slender rod of mass m and length L is pivoted about a horizontal axis through one end and released from rest at an angle of 30^@ above the horizontal. The force exerted by the pivot on the rod at the instant when the rod passes through a horizontal position is
