Calculate the kinetic energy of a squash ball travelling at 35 m/s.
The mass of the squash ball is 24 g.
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.
