A diver steps off a diving board 10.0m above the surface of a pool3.00m deep. What is the magnitude of the minimum acceleration(assumed constant) she must have in the water to keep her fromhitting the bottom? The answer is 33 m/s^2<br /><br/>
A) sketch a graph of velocity vs time.
B) for each of the seven relevant quantities below, relating to thefree fall part of the motion, either write it's known value withunits next to the equals sign, or write a question mark, if thequantity is unknown. Circle the unknown that you need to find, andcross out the one you don't need to find. ( it will requirejudgement on your part to determine what you need to know to solvethe problem)
t1=
t2=
ay=
y1=
y2=
(vy)1=
(vy)2=
C) write a kinematics equation in symbolic form (no numbers yet)that contains the unknown you need and does not contain unknown youdont need. Then show the equation (still in symbolic form) solvedfor the desired unknown. Then plug in the known values to show yourcalculation.
