An experimental drone of mass 4.8 kg is flying horizontally in a straight line.
Calculate the kinetic energy of the drone when it is travelling at a constant speed of 12.5 m/s.
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.
