you drop a rock into the water below from height of 53 m. ( assume no air resistance.)
A. what is the acceleration of the rock as it falls?
B. how long does it take to hit the water?
C. How much more time would it take if instead of dropping the rock straight down, you threw it horitontally with a speed of 5 m/s? explain
D. you throw another rock at an angle of 30 degrees above the horizontal with the speed of 12 m/s. what are the x- and y-cmponents of the rock's speed?
