Calculate the kinetic energy of a 2 kg object moving at 3 m/s

KE = 0.5 * m * v^2
where:
KE = Kinetic Energy
m = mass
v = velocity

m = 2 kg
v = 3 m/s

KE = 0.5 * (2 kg) * (3 m/s)^2

(3 m/s)^2 = 9 m^2/s^2

KE = 0.5 * 2 kg * 9 m^2/s^2
KE = 1 kg * 9 m^2/s^2
KE = 9 J

Therefore, the kinetic energy of the object is 9 Joules.
