Increasing the internal energy of the water

Reference no: EM13664641

Water of mass 0.75 kg is heated when it is stirred with a paddle that exerts a constant force of 5.20 N on the water and moves during it at a speed of3.40 m/s. How long will it take for the temperature of the water to increase by 1°C, if all the mechanical energy goes into increasing the internal energy of the water?
