A bullet of mass 10g travelling horizontally at 200 m/s strikes and embeds in a pendulum bob of mass 2.0kg.Assuming Specific heat capacity at constant volume (Cv) for the bob plus bullet is 3R, calculate the temperature increase of the system due to the collision. Take molecular mass of the system to be 200g/mol.
