Explanation:
momentum = mass × velocity
mass = 9.11 × 10^-31
velocity = 0.8725 multiplied by c ( which is the speed of light )
therefore velocity = 0.8725 × 3 × 10^8 = 2.6175 × 10^8 m/s
[tex]m = 9.11 \times 10 {}^{ - 31} \times 2.6175 \times 10 {}^{8} [/tex]
[tex]m = 9.11 \times 2.6175 \times 10 {}^{ - 31 + 8} [/tex]
[tex]m = 23.85 \times 10 {}^{ - 23} kgms {}^{ - 1} [/tex]
