I don't understand the language.....
With the values you've given, only velocity can be found.
Acceleration is rate of change of velocity
d= 250s
t= 17s
a= d/t
=
= 4.7
It can be calculated solely by knowing the vertical component of the velocity of projection.
The amount of time a projectile stays in the air only depends on its movement in the vertical direction, which is dependent on the vertical component of its velocity.
