V = u + at
o = u + 29
u = 20ms^-1
o = u + 29
u = 20ms^-1

so its initial velovity is 20 m/s

maine -2 liya hai kyuki question me retarted likha hai to ye negative acceleration hoga
why you substitute v = o
because applying break
when car applied brake it final velocity will be 0
v means final velocity
