Plizzz only have 10 minutes to turn !

I wouldn't take my word for it, but I believe you would use 106=0.5(.148)v^2.

This would lead to the answer being v=37.84749. (and v=-37.84749)

Not sure if you would round, but if so, 38. (Probably safe to leave it at 37.84m/s)

When you say atmospheric pressure it is a standard on all places on earth. The value of standard atmospheric pressure is 1 Bar approximately or 14.7 lb per square inch. This pressure is an attribute of free molecules on the air which is not bound the accumulation of the pressure of this in average is the atmospheric pressure.
