An autonomous marine survey drone has a total mass of 35 kg. During an observation run, it skims across the ocean surface at a constant speed of 14 m/s.
Calculate the kinetic energy of the drone during this run.
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×speed282 exam-style questions on Edexcel GCSE Physics 3.1 Energy stores and calculations. Each one has a worked solution and a mark scheme showing where the marks go.
