Please Help, It's Science 1. The wind pushes a paper cup along the sand at a beach. The cup has a mass of 25 kg and accelerates at a rate of 5 m/s2. How much force is the wind exerting on the cup?

2. You push a friend sitting on a swing. She has a mass of 50 kg and accelerates at a rate of 4 m/s2. Find the force you exerted.

3. How much force would it take to push another, larger friend who has a mass of 70 kg to accelerate at the same rate of 4 m/s2?

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?
