A bullet of mass \(5 g\), traveling with a speed of \(210 m / s\), strikes a fixed wooden target. One half of its kinetic energy is converted into heat in the bullet while the other half is converted into heat in the wood. The rise of temperature of the bullet if the specific heat of its material is \(0.030 cal /\left( g -{ }^{\circ} C \right)\) (1 cal \(=4.2 \times 10^7\) ergs) close to: \(\quad\)
