suvat only works for constant acceleration and you can tell from the diagram this is not constant acceleration as the line is not straight throughout

This is the simple question. We have to use area of trapezium to find u.
but can we use S =1/2(u+v)t here?
u=u v=0 t=23
it gives different answer?

thankyou
You can only use that for one part of the graph not both. SUVAT equations only work given the accelaration is constant, here the acceleration changes after 15 seconds so you cant do that.
