*FREE FALLING OBJECTS*
Q. A boy stands at the edge of a bridge 20.0 m above a river
and throws a stone straight down with a speed of 12.0 m/s.
He throws another pebble straight upward with the same
speed so that it misses the edge of the bridge on the way
back down and falls into the river. For each stone find (a)
the velocity as it reaches the water and (b) the average
velocity while it is in flight.
Note: Ignore the affects of air resistance.
THERES SO MANY FORMULAS FOR VELOCITY WHICH ONE AM I SUPPOSE TO USE? PLEASE HELP
