Use the rock key in the question to help you... Look at this image, what was happening in this areas past? options:

the water level was shallow beach, then it rose to deep sea, then the water receded to a beach

water was deep and then kept getting shallower and shallower until there was no water in the area

the water level was shallow beach, then it rose to shallow sea, then the water receded to a beach

the area was covered by a shallow sea the whole time

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
