The sketch of a bow is .50m. Compute the magnitude of the acceleration of an arrow fired from the bow having a speed of 20m/s; supposing the arrow experiences a constant acceleration above the 0.50m distance before leaving the bow. When the arrow is shot vertically upward and leaves the bow at a distance of 1.6m from the ground, determine the maximum height to which the arrow increases, and the net time of flight until the arrow strikes the ground.
