Question

whats wrong with this graph?

Answer 1

I think that the third and fourth pulses in the acceleration graph don't match the shape of the velocity graph. This could make the final part of the v-t graph "upside down". The third acceleration pulse would increase the velocity, the final deceleration pulse would "brake the thing to a stop". It's a bit of a head banger for me, but I think that may be right.
