Object 2 has more kinetic energy
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion, and it is given by

where
m is the mass of the object
v is its speed
In this problem, for object 1:
m = 2 kg
v = 2 m/s
So its kinetic energy is

For object 2,
m = 4 kg
v = 3 m/s
So its kinetic energy is

Therefore, object 2 has more kinetic energy.
