Use the equation: weight = spring constant × extension [2 marks] Weight = N 0 1 . 4 Calculate the elastic potential energy stored in the extended spring. Use the equation: elastic potential energy = 0.5 × spring constant × (extension)2 [2 marks] Elastic potential energy = J 5 *05* Turn over ► IB/M/Jun23/8464/P/2F Do not write outside the 0 1 box . 5 If there is more than one person on the chair, the spring could become inelastically deformed. What is meant by ‘inelastically deformed’? [1 mark] Tick () one box. The spring extends more when two or more forces act on it. The spring will not go back to its original length when the force is removed. The spring extends so that it is twice as long as its original length.

The black box records the distance travelled and the time taken for each journey. Figure 3 shows the distance–time graph for part of a journey. Figure 3 0 2 . 1 Which feature of Figure 3 shows that the car travels at a constant speed for the first 4 seconds? [1 mark] Tick () one box. The line becomes horizontal. The line goes through the origin. The line is straight. 11 *11* Turn over ► IB/M/Jun23/8464/P/2F Do not write outside the 0 2 box . 2 After 4 seconds the driver applied the brakes and the car slowed down and stopped. The distance the car travelled after the brakes were applied is called the braking distance. Determine the braking distance of the
