Or the aircraft P relative to aircraft Aman travelling along a straight track starts from rest at point
A and accelerates uniformly to 20
min 20s. It travels at
this speed for 60s, then slows down uniformly to rest in 40s
a point it stays at rest at C for 30 s, then reverses direction,
accelerating uniformly to 10ms'in 10 s. It travels at this speed
for 30 s, then slows down uniformly to rest in 10s when it
reaches point B
a Plot a graph of the motion of the train
b Use your graph to calculate:
i the train's displacement from point A when it reaches
point C
il the train's displacement from point A when it reaches
point B
in the train's acceleration each time its speed changes.​
