What was the KE of an 8 kg mass at 11 m/s

You must already know that KE stands for Kinetic Energy, which equals
(1/2) M V^2

M and V are mass and velocity, which are
M = 8 kg, and
V = 11 m/s
in this case.

Do the calculation with those numbers to get the answer in kg*m^2/s^2, which is also called Joules.
