Answer:
(a) Uniformly accelerated motion because velocity is increasing by equal amounts in equal intervals of time.
(b) Quantity is acceleration.
Acceleration = y - axis / x - axis
Acceleration = velocity / time
(c) Area of triangle = 1 / 2 × height × base
= 1 / 2 × velocity × time
(d) Distance (s) = Area under the graph
(s) = 1 / 2 × 15 × 30 = 225 m
