What is the intial velocity of the projectiles

Two identical launchers fire projectiles with the same initial velocity. One launcher is 3.54m above the ground and fires horizontally. The other launcher is on the ground and fires its projectile at an angle. Both projectiles travel 7.31m horizontally (though they are in the air different amounts of time).

a) How long does it take for the horizontally fired projectile to hit the grounf?

b) what is the intial velocity of the projectiles?

c) Determine one possible angle of launch for the projectile on the ground. (Since it is not a max range, there are two possible answers.)
