  4. A superball is released from a hand and falls for three seconds.
    1. __________ _____ Using the equation d = ½gt² and an acceleration of gravity g = 979 cm/s², how far does the superball fall in centimeters?
    2. __________ _____ At the end of the three seconds, what is the speed of the superball?
  5. A superball falls for 700 centimeters from the height of the new windows in the gym.
    1. __________ _____ How long does the superball fall in seconds if the acceleration of gravity g is 979 cm/s²?

slope= ( y2 − y1 ) ( x2 − x1 )
ѵ= Δd Δt
distance d = velocity ѵ × time t
ѵ = at
ѵ = gt
d = ½at²
d = ½gt²
where g is the acceleration of gravity
g = 979 cm/s²
