It would be better that you upload a better quality pic of the question.
For question 3, it seems that you have used 22 ns instead of the the question stated duration 0.22 ns. It may be better that you state what are the book's answers. I cannot figure out what question 4 is asking as the pic quality is not that clear.

Of course, that seems to be exactly what the problem is. Thx
idk what i'm doing wrong but i keep getting the change in momentum as -4.2*10^-22kgm/s. change in momentum=mv-mu ((5x10^-25)x-420)-((5x10^-25)x420)= -4.2x10^-22kgm/s
Force=change in momentum/time -4.2x10^-22/0.22x10^-9 F=1.9x10^12N
