Answer:
The answer to your question is v = 214. 25 m/s
Explanation:
Data
m = 6.1 x 10⁴ kg
Kinetic energy = Ke = 1.4 x 10⁹ J
v = ?
Formula
Kinetic energy = Ke = 1/2 mv²
solve for v
v² = 2Ke/m
Substitution
v² = 2(1.4 x 10⁹)/6.1 x 10⁴
Simplification
v² = 2.8 x 10⁹ / 6.1 x 10⁴
v² = 4.59 x 10⁴
v = [tex]\sqrt{4.59 x 10^{4}}[/tex]
Result
v = 214. 25 m/s
