Question

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?

Answer 1

yes
at each second
v = previous v + 9.81

Distance down = previous distance down + previous v + 4.9

Answer 2

Distance down = previous distance down + previous v * 4.9

Answer 3

Distance down = previous distance down + previous v * 1 + 4.9 * 1^2
