A projectile traveling at 100 meters per second is stopped by being shot into an insulated tank containing 400 kilograms of water. Kinetic energy of the projectile is completely converted into thermal energy. If the temperature of the water is raised by 0.05 degree C, what is the mass of the projectile? The specific heat of water is 4.18 Joules per gram per degree C.
