A skateboarder is coasting along a flat path at a steady speed of 8 m/s.
The skateboarder and skateboard have a total mass of 55 kg.
Calculate the kinetic energy of the skateboarder and their skateboard.
Use the equation:
kinetic energy=0.5×mass×(speed)2 \text{kinetic energy} = 0.5 \times \text{mass} \times (\text{speed})^2 kinetic energy=0.5×mass×(speed)2
