A bullet of mass 10 g moving with `300m//s` hits a block of ice of mass 5 kg and drops dead. The velocity of ice is

A bullet weighing 10 g and moving with a velocity 300 m/s strikes a 5 kg block of ice and drop dead. The ice block is kept on smooth surface. The speed of the block after the the collision is

A bullet of mass 10 g moving horizontally with a speed of 400 m//s a block of mass 390 g and remains in it. The block slides 10 m on rough surface before coming to rest. The friction coefficient is

A bullet of mass 10 g moving with a speed of 20 m//s hits an ice block of mass 990 g kept on a frictionless floor and gets stuck in it. How much ice will melt if 50% of the lost kinetic energy goes to ice? (Temperature of ice block = 0^@C .)

A bullet of mass 10 g moving with a speed of 20 m/s hits an ice block of mass 990 g kept on a frictionless floor and gets stuck in it. How much ice will melt if 50\% of the lost KE goes to ice? (initial temperature of the ice block and bullet = 0^(@)C )

A bullet weighing 10 gm and moving at 300 m/s strikes a 5 kg ice and drops dead. The ice block is placed on a frictionless level surface. The speed of the block after the collision, is
