Question 3

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×speed2
