A train travelling along a straight track starts from rest at point A & accelerates uniformly to 20m/s in 20s. it travels at this speed for 60s, then slows down uniformly to rest in 40s at point C. it starts at rest at C for 30s, then reverses direction, accrlerating uniformly to 10m/s in 10s. it travels at this speed for 30s, then shows 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:
1.the train's displacement from point A when it
reaches point C
2.the train's displacement from point A when
it reaches point B
3,the train's acceleration each time its speed
changes
