You shoot an arrow straight up at 50 meters per second. When will it run out of speed?
:
Assume you mean the point when it reaches it's highest point, it stops and changes to a downward direction.
At that point gravity (-4.9t^2) takes over, upward velocity, is 0.
:
h = -4.9t^2 + 50t
the axis of symmetry of this equation gives the time of maximum height
t =
t =
t = 5.1 seconds
