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.
Unreasonable results A dolphin in an aquatic show jumps straight up out of the water at a velocity of 15.0 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 a time is the dolphin in the air? Neglect any effects resulting from his size or orientation.
I did a lab based Projectile Motion and they ask me this question
Following the definitions of direct and inverse proportionality earlier, discuss why this equation shows that your answers for initial velocity and gravity are correct.
* Note that this range equation only works if y0 = yf
I think is because of the no air resistance but im not sure can you help me this one I don't want to know if I'm right or wrong?

In the 1980s, one of Asia's fastest running women was a Filipino athlete names Lydia de Vega. In the 100 meter dash event in 1986 in Seoul, South Korea, she was clocked 11.53 s. Find her average speedarrow_forwardthis is the problem that I was given. I am asked to find the horizontal distance to collision which I found by distance/height=tan(theta). I am asked to calculate time ofcollision which I did by taking distance/speed (in km/s). I am also asked to calculate the constant A from the accleration equation. I find A by taking the intgral of the acceleration twice to find my position formula. I plug in zero for t to get A/b^2=position. I find position by taking pythagorean theorem of height and distance, then multiply what I get by b^2.
