An archer stands 42.0 m from the target. If the arrow is shot horizontally with a velocity of 95.0 m/s, how far above the bull's-eye must he aim to compensate for gravity pulling his arrow downward? A beach ball, moving with a speed of +1.30 m/s rolls off a pier and hits the water 0.73 m from the end of the pier. How high above the water is the pier? I need some help with these.
