5) A train travels up a mountain carrying skiers in winter and tourists in
summer. A velocity time graph describes the train’s motion.
a) Calculate the acceleration of the train in the first 200s.
b) Calculate the total length of the journey.
6) A cyclist starts at rest and accelerates to a speed of 5ms
-1
in 2 seconds.
He then travels at a constant speed for 5 seconds before coming to a
stop in 3 seconds.
a) Draw the speed time graph of the journey (on graph paper).
b) Calculate the acceleration of the cyclist during the first part of the
journey.
c) Calculate the total distance the cyclist travelled over the journey.
