The answer has been provided to three significant figures to correspond with the number of sig figs given in the mass.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
