During a cycle race,two persons `A` & `B` moving with velocity 16m/s & 12m/s respectively.At t=0,B observes A, 10m ahead of him, in order to win the race they start accelerating at `1m/s^(2)` and `2m/s^(2)` respectively.Unfortunately both finish simultaneously.The time (in sec) at which they finish the race is equal to t (t=10k) ,then value of k is ?
