Answer:
Step-by-step explanation:
I wonder what level of physics you are taking? If this is a beginning course (which I'm going to assume) then the KE is
KE = 1/2 m v^2
KE = 1/2 * 2kg * (10 m/s)^2
KE = 100 Joules.
If you are in an upper level course and need to take into account the rotational motion, leave a note.
