A train accelerates uniformly from
rest at station A to a maximum speed
of 72km/h. The constant maximum
speed is maintained for a period of
time and the train then decelerate
uniformly until it comes to a stop at
station B. The distance between two
railway stations is 22km and the
journey takes 20min if the magnitude
of the acceleration is half that of
deceleration, by using graphical

The coefficient of kinetic friction between each mass and its incline is uk = 0.30. If ma moves up, and mB moves down, determine their acceleration.

Assume the rope can provide a tension force of up to 29 kN before breaking, and use a "safety factor" of 10 (that is, the rope should only be required to undergo a tension force of 2.9 kN).
