5A bullet moving with a uniform velocity v, stops suddenly after hitting the target and the whole mass melts be m, specific heat S, initial temperature `25^(@)C,` melting point `475^(@)C` and the latent heat L. Then v is given by

A bullet of lead melts when stopped by obstacle. Assuming that 25 per cent of the heat is absorbed by the osbtacle, find the velocity of the bullet if its initial temperature is 27^(@)C . (Melting point of lead 327^(@)C , specific heat capacity of lead =30 cal kg^(-1)K^(-1) specific latent heat of fusion of lead =6000 cal kg^(-1) and J=4.2 joules cal^(-1) )

A lead bullet just melts when stopped by an obstacle. Assuming that 25% of heat is absrobed by the obstacle find the velocity of the bullet if the initial temperature was 27^(@)C. Melting point of lead = 327^(@)C, specific heat of lead =0.03 cal g ^(-1) ""^(@)C ^(-1). Latent heat of fusion of lead =6 cal g ^(-1).

A lead ball moving with a velocity v strikes a wall and stops. If 50% of its energy is onverted into heat. The increase in temperature is (Specific heat of lead is S)

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 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 ball moving with velocity v strikes a wall and stops. iF 50% of its energy is converted into heat, then what will be the increase in temperature ? Specific heat of lead is s
