a kangaroo jumps to a vertical height of 2.8m. how long was it in the air before returning to earth.

I'm clueless on how to solve it. can someone help me please?

thanks in advance

d=2.8m

a= -9.8 m/s^2 (since it's going the opposite direction of gravity, right?)

i was wondering how you search for time with only these 2 quantities.
