Answer 1

Answer:

1,896,770,400J

Explanation:

The equation to find Kinetic Energy (KE) is

KE = $\frac{1}{2}$ m $v^{2}$

You are given

m = 480000kg

v = 88.9m/s

Substitute the values into the equation and solve for KE

KE = $\frac{1}{2}$ m $v^{2}$

KE = $\frac{1}{2}$ * 480000 * $88.9^{2}$

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