The formula for kinetic energy is KE = 1/2mv^2, where m is the mass of the object and v is its velocity. Rearranging this formula, we can solve for velocity: v = √(2KE/m).

Plugging in the given values, we get: 
v = √(2(20.00 J) / 3.000 kg)
v = √13.3333...
v = 3.6515 m/s

The formula for momentum is p = mv, where p is momentum and m and v are the mass and velocity of the object, respectively. Plugging in the values we just found, we get: 
p = (3.000 kg)(3.6515 m/s)
p = 10.9545...
p ≈ 10.95 kg m/s

Therefore, the best choice is D: 10.95 kg m/s.
