Hey mate!
Here's your answer!!
Consider the graph shown in the given attachment. Obviously, the total distance s travelled by the object in time t is given by are under v-t graph.
Therefore, distance travelled, s = Area OABGC
Obviously, OABGC is a trapezium, whose area is (OA + BC/2) × OC.
But, OA = u, BC = v and OC = t
Distance travelled,
From the velocity - time relation, we have
at = v - u or t = v - u/a
On substituting this value of t in equation, we get
➡ v² - u² = 2as
Therefore, this equation is the position velocity relation for uniformly accelerated motion.
Hope it helps you!
