    Solution Preview

    The proton mass is equal to:

    1.67262158 × 10-27 kilograms

    The kinetic energy of the proton is given by:

    (1/2) Mass X Velocity ^2

    (1/2)mV^2

    The proton will came to rest when the kinetic energy equal to the ...

    Solution Summary

    The potential energy to stop or slow a proton is determined.
