A thinuniform circular disc of mass M and radius R is rotating in a horizontal plane about an axis passing through its centre and perpendicular to its plane withan angular velocity omega .Another disc of same dimensions but of mass M/4 is placed gently onthe first disc co-axially, then the angular velocity of the system is

A bullet of mass 10g moving horizontally with a velocity of 400 ms^(-1) strikes a wooden block of mass 2 kg which is suspended by a light inextensible string of length 5m . As a result, the center of gravity of the block is found to rise a vertical distance of 10cm . The speed of the bullet after it emerges out hirizontally from the block will be

Auniform disc of mass M and radius R is rotating in a horizontal plane about anaxis perpendicular to its plane with an angular velocity omega . Another disc of mass M/3 and radius R/2 is placed gently on the first disc coaxially. Then final angular velocity of the system is

A bullet is fired from surface of earth with a velocity of u m/s at an angle theta with the x-axis. Simultaneously a similar bullet is fired from a certain plant with velocity u^' m/s at the same angle with the direction of x-axis. The trajectories in the two cases are identical. If g and g^' are accelerations due to gravity on the curth's surface and planet's surface respectively, then
