Force of 50 n is applied to a 100 kg boulder, which starts at rest and moves 5.5 meters accross a level frictionless cliffside that is 12 meters high. how fast is the boulder moving when it leaves the cliff?

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?
