Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get

Putting values in this equation, we get:

Thus, the object is moving with a velocity of 1.33 m/s
