a) when particle A hits the ground, it does not bounce. Find the max height reached by particle B

b) when particle A hits the ground, the string is cut. Find the total time from being released from rest until B hits the ground.

I calculated (a) and got the max height traveled by B when A hits the ground would be 1.2 +1.2 +0.27= 2.68m

Iam not getting the right ans for (b) which is 1.99 s

t1= 1.02s

When the string is cut, Tension=0N , max height reached by B =2.68m, a=-g=-10m/s^2, u=0m/s on the way down.
