As a car passes point A on a straight road, it's speed is 10m/s, the car moves with constant acceleration, a m/s/s, along the road for T seconds until it reaches point B, where it's speed is Vm/s.

The car travels at this speed for a further 10 seconds, when it reaches the point C. From C it travels for a further T seconds with constant acceleration 3a m/s/s until it reaches a speed of 20 m/s at the point D.

Sketch the [t,v] graph for the motion, and show that V=12.5

However part B states,

The distance from A to D is 675m, find a and T

Any help will be so very greatly appreciated!

Thanks in advance

**I had no problem with showing V = 12.5 through a simultaneous equation.**However part B states,

The distance from A to D is 675m, find a and T
