Answer:

1,896,770,400J

Explanation:

The equation to find Kinetic Energy (KE) is

KE = [tex]\frac{1}{2}[/tex] m [tex]v^{2}[/tex]

You are given

m = 480000kg

v = 88.9m/s

Substitute the values into the equation and solve for KE

KE = [tex]\frac{1}{2}[/tex] m [tex]v^{2}[/tex]

KE = [tex]\frac{1}{2}[/tex] * 480000 * [tex]88.9^{2}[/tex]

KE = 1,896,770,400 Joules(J)
