The solution has been excellently provided by @aankurverma

Given,
v0 = v0 j
a = k(v x A)
A = (-c/y) k

Now,
a = (kc/y)vx j  - (kc/y)vy i
vy.dvy/dy = (kc/y)vx = (kc/y)(v2 - vy2)
At maximum height, ym, the y component of velocity is zero.
v00 [vy/(v2 - vy2)]dvy = kc y0ym (1/y)dy
Integrating you should get the answer.
