2 CHIJSec/2025/OLevelPrelim/6091/02 Section A Answer all the questions in this section. 1 A small spacecraft, known as Mars Express, is to land on the planet Mars. As the spacecraft enters the planet’s atmosphere, it slows down. When the speed reaches 400 m/s, parachutes open and friction with the atmosphere increases. The spacecraft eventually reaches a steady speed, and then finally it hits the surface. (a) On the axes of Fig. 1.1, complete the speed-time graph for the spacecraft. The parachutes open at time t1, and the spacecraft hits the surface of Mars at time t2 . [2] Fig. 1.1 (b) State what is meant by a gravitational field. …………..……………………………………………………………………………………………… …………..……………………………………………………………………………………………… ………………………………………………………………………………………………………..[1] (c) The mass of the spacecraft is 65 kg. At one point the gravitational field strength of Mars is 3.0 N/kg and the total upwards force on the spacecraft is 500 N. Determine (i) the weight of the spacecraft, weight = ………………..…………[1] (ii) the resultant force on the spacecraft, resultant force = ………………..…………[1] (iii) the deceleration of the spacecraft. deceleration = ……….…………………[2] [Total: 7] time / s speed m/s 0 t1 t2 400
