At a water park, a 50kg lady goes down a water slide. At a point 3m above the plash-down pool, the lady passes a radar type speedometer that determines the lady's speed is 12m/s.
a. calculate the ladys KE and PE with respect to splash down pool when passing the speedometer. 9.8 for gravity.
b. expalin how the energies you calculate compare to the ladys KE and PE just before landing in the splash down pool.
