As seawater flows through a tidal turbine generator, the kinetic energy of a 18.0 kg mass of moving water is 576 J.
Calculate the speed of this water as it passes through the turbine.
Use the equation:
kinetic energy=0.5×mass×speed2 \text{kinetic energy} = 0.5 \times \text{mass} \times \text{speed}^2 kinetic energy=0.5×mass×speed2Show your working.
