Adolphin in an aquatic show jumps straight up out of the water at a velocity of 11.8 m/s. the magnitude of the gravitational acceleration g = 9.8 m/s2 take the water surface to be y0 = 0. choose upward as positive y direction. keep 2 decimal places in all answers. (a) how high (what maximum height) in meters does his body rise above the water? to solve this part, first note that the body's final velocity at the maximum height is known (implicitly) and identify its value. then identify the unknown, and chose the appropriate equation (based on the knowns and unknown) to solve for it. after choosing the equation, solving for the unknown, checking units, think about whether the answer is reasonable.(b) how long in seconds is the dolphin in the air? neglect any effects due to his size or orientation. note: this is the total time of jumping up from water to hightest point and falling down to water.
