Explanation:
K.E = 5,000,000 KJ
MASS = 100,000,000 Kg
K.E = 1/2 MV^2
[tex]5000000 = \frac{1}{2} \times 100000000 \times v {}^{2} [/tex]
[tex]5000000 = 50000000 \times v {}^{2} [/tex]
[tex]v {}^{2} = \frac{5000000}{50000000} [/tex]
[tex]v {}^{2} = \frac{5}{50} [/tex]
therefore
[tex]v {}^{2} = \frac{1}{10} [/tex]
[tex]v = \sqrt{0.1} [/tex]
v = 0.316 m/s^2
