8ai) Apply formula for acceleration and you find it, simple!
8aii) Find acceleration between t=6 and t=15, use that acceleration,equate with (v-12) / (13-6).
8aiii) All area under curve from t=1 to t=15. Triangle, trapezium and rectangle.
8b) acceleration of truck = (v-0) / (15-5)
8c) Curve from origin with decreasing gradient and then a positive slope
