1. An object moving vertically in free fall has an initial velocity vi m/s, starts at y=0, and rises to a height of y=h. vi= 27 m/s Positive numbers are in the upward direction, and the object may drop below its initial position.

2. An object moving vertically in free fall has an initial velocity vi m/s, starts at y=0, and rises to y=h in t seconds, reaching a final velocity of vf m/s. Find yf if:vi= 38 m/s t= 1.5 s

Positive numbers are in the upward direction, and the object may drop below its initial position.

3. An object moving vertically in free fall has an initial velocity vi m/s, starts at y=0, and rises to y=h in t seconds, reaching a final velocity of vf m/s. Find vf if:vi= 38 m/s t= 6.9 s

positive numbers are in the upward direction, and the object may drop below its initial position.
