Step-by-Step Solution:
Step 1 of 3

Free Fall Motion:  Moving object are only influenced by gravity  Acceleration due to gravity (g) is constant (+9.81 m/s ) o g is always positive o Gravity always pulls objects downward  g is independent of mass  If there is no resistance, then all object will fall with the same acceleration Object moving upward Object moving downward Acceleration= -g Acceleration=g v = v – gt v v + gt f i f = i 2 2 y f y i +vi – ½ gt yf =y i +vi + ½ gt v f=– igΔy vf=v +2 iΔy
