Task 1 Intercity-Express (ICE) The German rail service has a fleet of ICE trains, which is a collection of high speed trains. With a maximum speed of up to 330 km/h (approximately 91.7 m/s) these are Germany's fastest trains. They are approximately 200 metres long and weigh around 400 tonnes. Each train is made up of eight carriages. Trial journeys are carried out for acceleration and braking tests. The results of these tests can be represented graphically.
b) Data was collected during a braking test. This data can be described by the distance covered, s(t), as a function of time, t, as s(t) = 70. [-0.25 · t?, where t is in seconds and s(t) is in metres from the start of braking. = > Determine the time-velocity function, V2, for the braking test in the form vz(t) = m .t+c and explain the meaning of the parameters m and c in terms of the context described above. Determine the distance the ICE covered from the start of braking until the standstill.
