A dolphin in an aquatic show jumps straight up out of the water at a velocity of 13.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known and identify its value. Then identify the unknown, and discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long is the dolphin in the air? Neglect any effects due to his size or orientation.

Step-by-step solution 45PE Step 1 of 4 The formula that can be used is, Here, y is the final position, yo is the initial position, u is the initi l velocity, is the time i terval and a is the acceleration of the body. Step 2 of 4 (a) The known quantities are, The initial velocity u of the dolphin is 13.0 m/s . The acceleration a of the dolphin is the acceleration due to gravity and is .The initial position yo or height of the dolphin is 0 m.
