Context for question 3
A rollercoaster carriage of mass 280 kg travels over a raised section of track, as illustrated in Figure 3.1.
Figure 3.1, a rollercoaster carriage of mass 280 kg on a raised section of track between points X and Z, with the track rising to a peak at Y; dashed horizontal lines from the level of X and Z up to Y show the height difference $\Delta h$ between the peak and that level, marked not to scale
At position X, the carriage has kinetic energy 16.1 kJ. At position Y, the carriage has kinetic energy 1.3 kJ. The length of track between X and Y is 23 m. In moving from X to Y the carriage does 5.1 kJ of work against resistive forces.
3(a)(i)Energy Work Power EfficiencyEasy2 marks
Calculate the average resistive force acting on the carriage between X and Y.

Answer

3(a)(ii)Energy Work Power EfficiencyMedium3 marks
Calculate the change in height between X and Y.
3(b)Energy Work Power EfficiencyMedium1 mark
The carriage travels further along the track to point Z. State and explain whether the speed of the carriage at Z is greater than, less than or the same as the speed of the carriage at X.
