In the vertical jump, an athlete starts from a crouch and jumps upward as high as possible. Even the best athletes spend little more than 1.00 s in the air (their ""hang time""). Treat the athlete as a particle and let [math]y_{\max }[/math] be his maximum height above the floor. To explain why he seems to hang in the air, calculate the ratio of the time he is above [math]y_{\max } / 2[/math] to the time it takes him to go from the floor to that height.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
