Kingda Ka in the United States is the world's tallest rollercoaster. A motor pulls a cable attached to the train, acceleratingit at 16,3 m.s–2 from rest at point Oto 57,2 m.s–1 along a
horizontal track. At the end of the launch track(A) the train climbs the main tower reachingB at a vertical height of 139 m above the bottomof the track.
1. Calculate the time taken for the train to reach a speedof 57,2 m.s-1 during the horizontal launch fromO to A.
2. Over what horizontal distance does this accelerationtake place?
3. If the mass of the Kingda Ka train and riders is 8 500kg then how much work is done by the net force on the train toaccelerate it from rest to 57,2 m.s-1?
4. Would the work done by the cable on the train during thehorizontal launch from rest to 57,2 m.s-1 be GREATERTHAN, LESS THAN or EQUAL TO the value calculated inQUESTION 3? Explain.
