3. A 0.145 kg ball moving horizontally at 20 m/s is struck by a bat that causes the ball to move in the opposite direction at 15 m/s. If the ball and bat were in contact for 5 ms, how much force did the bat
apply to the ball?

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?
