Mechanical energy goes into increasing internal energy-water

Reference no: EM13664461

Water of mass 2.00 kg is heated when it is stirred with a paddle that exerts a constant force of 6.50 N on the water and moves during it at a speed of 1.80 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?
