A golf ball rolls uphill toward a mini-golf hole. Assume that the direction toward the hole is positive. If the ball starts with a speed of 2.0 m/s and slows at a rate of 0.50 m/s^2, what is its velocity after 2.0 seconds?

What are the phases shown in a and d called?

Which sections of the heating curve illustrate this process?

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?
