Shadow · Answer

$$KE = \frac{ 1 }{ 2 }mv^2$$

Where KE is equal to 1/2 of mass times velocity squared

hallm · Answer

wha?

dude · Answer

KE = Kinetic Energy
m = mass
v = velocity

$KE=\frac12mv^2$

We know:
m = 2000 kg
v = 22 m/s

Substitute the values given into the equation that Shadow gave you
