Q. No.A \(100\) g of iron nail is hit by a \(1.5\) kg hammer striking at a velocity of \(60\) ms–1. What will be the rise in the temperature of the nail if one-fourth of the energy of the hammer goes into heating the nail?
[Specific heat capacity of iron = \(0.42\) Jg–1 °C–1]
[Specific heat capacity of iron = \(0.42\) Jg–1 °C–1]
