Use velocity- time graph of a particle to prove first and second equation of motion​

1. Answer:

   At t = 0, initial velocity = u = OA

   At t = t, final velocity = v = OC

   The distance S travelled in time t = area of the trapezium OABD

   s = (1/2) x (OA + DB) × OD

   s = (1/2) x (u + v) × t

   Since v = u + at,

   s = (1/2) x (u + u + at) × t

   s = ut + (1/2) at2
