A proton with mass 1.67 times 10^{ -27};{rm kg} is propelled at an initial speed of 3.00 times 10^{5};{rm m}/{rm s} directly toward a uranium nucleus 5.00 {rm m} away. The proton is repelled by the uranium nucleus with a force of magnitude F=alpha/x^{2}, where x is the separation between the two objects and alpha =2.12 times 10^{ -26};{rm N} cdot {rm m}^{2}. Assume that the uranium nucleus remains at rest.Give your answer in m/s in scientific notation to three significant digits (i.e. 1.15*10^2)Note: The numbers given in this problem do not represent actual figures, instead this is to be thought of as a theoretical calculation.
