An experimental high-speed magnetic sled, with a mass of 12,500 kg12,500\text{ kg}12,500 kg, is travelling along a horizontal test track at a velocity of 80 m/s. To bring the sled to a complete stop, an electromagnetic braking system is engaged, exerting a constant resisting force of 250,000 N250,000\text{ N}250,000 N.
Determine the distance travelled by the sled during this braking phase.
Practise AQA GCSE Physics Forces and motion with exam-style questions for Foundation and Higher tier. 83 questions covering Describing motion along a line, Forces, accelerations and Newton's Laws of motion, and Forces and braking, matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
