What is their solution??

The main difference is they say y=1.8 when t=0, whereas for your solution you have y=0 when t=0.

It doesn't mean your solution is wrong though.

Either way you still get the same answer.

I think that's because I let the origin be up at 1.8m (I.e. y=0) so when the droplet falls it's at -1.8; whereas they let the droplet at ground level be 0 so origin is y=1.8
