A 2 g bullet moving with a velocity of 200 m/s is brought to a sudden stoppage by an obstacle. The total heat produced goes to the bullet. If the specific heat of the bullet is `0.03 cal//g^@C`, the rise in its temperature will be

A lead bullet of mass 50g moving with a velocity of 100ms^(-1) strikes a target. If 40% of the heat produced is retained by the bullet, calculate the rise in its temperature. Specific heat of lead = 0.03 cal g^(-1)K^(-1) and J = 4.2 J cal^(-1)

A lead bullet strikes against a steel plate with a velocity 200ms^-1 . If the impact is perfectly inelastic and the heat produced is equally shared between the bullet and the target, thent he rise in temperature of the bullet is (specific heat capacity of lead =125Jkg^-1K^-1 )

A bullet moving with a speed of 200 " m s"^(-1) is absorbed by a wooden block of mass 1500 g suspended by a string . Caclulate the vertical height through which the block will rise . The mass of the bullet is 20 g .

A hunter fired a metallic bullet of mass 'm' kg from a gun towards an obstacle and it just melts when it is stopped by the obstacle. The initial temperature of the bullet is 300 K . If 1/4 th of heat is absorbed by the obstacle, then the minimum velocity of the bullet is Melting point of bullet=600 K Specific heat of bullet = 0.03 cal g^-1^@C^-1 , Latent heat of fusion of bullet= 6 cal g^-1 ]

A lead bullet weighing 20 g and moving with a velocity of 100 ms^(-1) comes to rest in a fixed block of wood. Calculate the heat developed and the rise in temperature of the bullet assuming that the half of the heat is absorbed by the bulley. The specific heat of lead is 0.03 cal g^(-1).^(@)C^(-1) .

A bullet moving with a velocity of 230 m/s is stopped by a block of wood. Calculate the rise in temperature of the bullet assuming that all the heat generated is retained by the bullet. Specific heat capacity of lead = 126 J/kg/K.
