A cyclist is moving up a slope that has a constant gradient. The cyclist takes 
to climb the slope. The variation with time 
of the speed 
of the cyclist is shown in the figure below:
Use the above figure to determine the total distance moved up the slope.
The bicycle and cyclist have a combined mass of 
. The vertical height through which the cyclist moves is 
. For the movement of the bicycle and cyclist between 
and 
use the figure above to calculate the change in kinetic energy,
