Answer:

[tex]\huge\boxed{K.E. = 675,000\ Joules}[/tex]

Explanation:

Given Data:

Mass = m = 1500 kg

Speed = v = 30 m/s

Required:

Kinetic Energy = K.E. = ?

Formula:

[tex]\sf K.E. = \frac{1}{2} mv^2[/tex]

Solution:

K.E. = 1/2 (1500)(30)²

K.E. = (750)(900)

K.E. = 675,000 Joules

[tex]\rule[225]{225}{2}[/tex]

Hope this helped!
