A hammer of mass '

1

kg

having speed of

50\,m/s

, hit a iron nail of mass

200\,gm

. If specific heat of
iron is

0.105\,\,cal/g{m^0}C

and half the energy is converted into heat, the raise be temperature of nail is

View answer and explanation

Correct option: A

{7.1^0}C

Option A (

{7.1^0}C

) is correct because it represents the temperature rise calculated by equating half of the hammer's kinetic energy to the heat gained by the nail.
