We have: K.E. = mv² / 2
Here, m = 1868 Kg
v = 18 m/s

Substitute their values into the expression:
K.E. = (1868)(18)² / 2
K.E. = (1868 × 324) / 2
K.E = 605232 / 2
K.E. = 302616 J

In short, Your Answer would be 302616 Joules

Hope this helps!

Ke = 1/2(m)(v^2)

Ke = 1/2(1868)(18^2)

Ke = (934)(324)

Ke = 302,616
