A soccer ball is kicked upward from the ground with an initial vertical velocity of 3.6 meters per second. After how many seconds does it land?

If you really want an expert to help you, be sure to follow directions and type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
The total time in the air (T), if kicked straight up at initial velocity Vo, is twice the time that it takes to reach zero velocity. Maximum height is reached at t = T/2

T = 2 Vo/g = 2*3.6/9.8 = 0.73 seconds
The same answer will apply if Vo is the initial vertical COMPONENT of velocity. That was probably the intent of the question.

I overloooked your question at first becasue I am not an expert on quails.
