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 ..............

One end of a straight uniform 1m long bars pivoted on horizontal table. It is released from rest when it makes an angle 30^(@) from the horizontal (see figure ) . Velocity of end point of the rod when it hits the table is given as sqrt( n ) ms^(-1) ,where n is an integer.The value of n is "_______________"

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) )

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

A projectile projected with initial velocity 20m/s and at and angle of 30^(@) from horizontal. Find the total work done when it will hit the ground.

A rod of length L is hinged from one end. It is brought to the horizontal position and released. The angular velocity of the rod when it is in the vertical position is sqrt(Kg//L) . Then find the value of K.

A projectile is fired from the top of an 80 m high cliff with an initial speed of 30(m)//(s) at an unknown angle. The speed when its hits the ground.

A uniform chain of length 1 and mass m is kept on a smooth table. It is released from rest when the overhaning part was n^(th) fraction of total length. Find the kinetic energy of the chain as it completely slips off the table
