If you shoot an arrow straight up at 50 meters per second when will it run out of speed?

The acceleration of gravity is 9.8 meters per second2. That means that any object with no forces acting on it other than gravity, gains speed of 9.8 meters per second downward every second.
Starting with speed of 50 m/s upward, the upward speed decreases by 9.8 m/s each second.
The upward speed is zero after (50/9.8) = 5.1 seconds (rounded)
That's the peak height that the arrow reaches. After that, it starts to fall.

You shoot an arrow into the air. Two seconds later the arrow has gone straight upward to a height of 33.0 m above its launch point. What is the arrow's initial velocity?
The acceleration of gravity is [9.8 meters per second2] directed downward.After two seconds of vertical flight, the upward speed of the arrow is (9.8 x 2) = 19.6 m/sless than its initial velocity.Average speed = 1/2 (Vi + Vf) = 1/2 (Vi + Vi-19.6) = Vi - 9.8Distance = (average speed) x (time) = 33(Vi - 9.8) x (2) = 33Vi - 9.8 = 16.5Vi = 16.5 + 9.8 = 26.3 m/s
