Asked by Ryan
Miss E. deWater, the former platform diver of the Ringling Brothers' Circus, dives from a 80.0-meter high platform into a shallow bucket of water (see diagram at right). Determine her speed and her height after each second of fall.
When t = 0 s: speed = 0 m/s and height = 80 m
Should I use kinematic equations to find acceleration then plug that in?

V = Vo + g*T.
Vo = 0.
g = 10 m/s^2.
h = ho - 0.5g*Tf^2 = 0.
5Tf^2 = 80.
Tf^2 = 16.
Tf = 4 s. = Fall time.
Use T in the range of 0 to 4 seconds.
(T,V,h).
(0,0,80).
(1,10,75).
(2,20,60).
(3,30,35).
