Suppose that it accelerated for x seconds
Then,
It retarded for 3-x s
initial velocity from start = 0
Final velocity = U + at
v = 2(x) = 2x
Initial velocity for Retarded part = 2x
Final velocity. = 0
v=u + at
0=2x -4(3-x)
4x-12 = 2x
x=2
v= u+at
=0+2×2
v=4 m/s
Hope it helps.
If it Mark as BRAINLIST.
