Hello frnd..
In the equation v = u + at
v ------> Final velocity...
u ------->Initial velocity..
a -------> Acceleration
t ---------> time
To derive the equation..
From the figure given..
Intial velocity u = AO ----------> 1
Final velocity v = BC = BD + DC = BD + u
v = BD + u
BD = v - u ---->3
To find acceleration..
a = Change in velocity ÷ Time
a = BD / AD
a= BD / t
BD = at -----> 4
Substitute BD in eqn 4..
at = v - u
v = u + at..
Hope it helps u frnd..
