07 07 1 Figure 9 shows part of a roller coaster with a train on the track. Figure 9 Train Track The train accelerates down the slope for 3.2 s. The change in velocity of the train is 25 m/s. Calculate the average acceleration of the train. Use the Physics Equations Sheet. Give your answer to 2 significant figures. Average acceleration (2 significant figures) = ==== [3 marks] m/s2
07 2 The total mass of the train is 4000 kg. Calculate the kinetic energy of the train when the train is travelling at 30m/s. Use the Physics Equations Sheet. Kinetic energy = Energy is transferred from the train to the track during the roller coaster ride. Name the force that causes energy to be transferred from the train to the track. [1 mark] Name the force that causes energy to be transferred from the train to the track. [1 mark] [1 mark] 07.3 07.3 07 4 What effect does this energy transfer have on the track? [2 marks]
07.5 The train decelerates to a stop. The average deceleration of the train is 9.5 m/s². The total mass of the train is 4000 kg. Calculate the average resultant force on the train as it decelerates. Use the Physics Equations Sheet. Average resultant force= [2 marks] N
