Answer:

Kinetic energy is just given by #E_k=1/2mv^2#. In this case, #E_k=1/2*1/2*64^2 = 1024# #J#

Explanation:

Not too much more to explain for this question. Kinetic energy is the energy something has because it has mass and is in motion, and is calculated using the equation #E_k=1/2mv^2#, where #E_k# is the kinetic energy #(J)#, #m# is the mass #(kg)# and #v# is the velocity #(ms^-1)#.
