A bullet of mass `20 g` moving horizontally strikes a block of mass `480 g` suspended by a string of length `2 m`. If the collision is completely inelastic , the minimum velocity of bullet , so that the combined mass complete vertical circle should be

A bullet of mass m moving with velocity u on smooth surface strikes a block of mass M kept at rest. The collision is completely inelastic. Find the common velocity and the fractional loss in kinetic energy.

A bullet of mass m moving with a horizontal velocity u strikes a stationary wooden block of mass M suspended by a string of length L = 50 cm. The bullet emerges out of the block with speed (u)/(4) . If M = 6 m, minimum value of u so that the block can complete the vertical circle (take, g = 10 ms^(-2) )

A bullet of mass m moving with a horizontal velocity u strikes a stationary wooden block of mass M suspended by a string of length L = 50 cm. The bullet emerges out of the block with speed (u)/(4) . If M = 6 m, minimum value of u so that the block can complete the vertical circle (take, g = 10 ms^(-2) )

A bullet of mass m moving with velocity v strikes a block of mass M at rest and gets embedded into it. The kinetic energy of the composite block will be
