The kinetic energy (KE) of an object can be calculated using the formula:

KE = 1/2 * m * v^2

where:
m is the mass of the object (in kg), and
v is the speed of the object (in m/s).

In this case, the mass (m) of the aardvark is 50 kg and the speed (v) is 6 m/s.

Substituting these values into the formula gives:

KE = 1/2 * 50 kg * (6 m/s)^2
= 1/2 * 50 kg * 36 m^2/s^2
= 900 Joules

So, the kinetic energy of the aardvark is 900 Joules. Therefore, the correct answer is D.900 J.
