I have a physics problem I have been trying to figure out for a week and I'm now to the point of way past frustrated. The question is:
An object with the mass 1.44*10^-27 kg is propelled at an initial speed of 3.84*10^5 m/s toward a fixed nucleus 4.80 m away. The object is repelled by the nucleus with the force F= a/x^2 where x is the separation between the object and the nucleus and a = 2.59*10^-26 Nm^2. What is the speed of the object when it is 7.46*10^-10 from the nucleus?
I have tried many ways to solve this to the point of I don't know what I'm doing anymore and just trying to plug in numbers into equations and still not getting the right answer of 3.15*10^5.
equations:
F=m*a
final speed^2=initial speed^2+2*acceleration*distance
