An electric scooter and its rider have a combined mass of 90 kg.
The rider travels along a flat, straight road at a steady velocity of 6 m/s.
Calculate the kinetic energy of the rider and scooter.
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×speed257 exam-style questions on Edexcel GCSE Physics 8.1 Energy transfers and work. Each one has a worked solution and a mark scheme showing where the marks go.
