What is the value of kinetic energy thickness?

A. <sup>**</sup> = ( int_0^ frac {u}{U_e} big [ )1 ( big ( frac {u}{U_e} big )^2 big ] )dy
B. <sup>**</sup> = ( int_0^ frac {u}{U_e} big [ )1 ( frac {u}{U_e} big ] )dy
C. <sup>**</sup> = ( int_0^ big [ )1 ( frac {u}{U_e} big ] )dy
D. <sup>**</sup> = ( int_0^ frac {u}{U_e} big [ )1 + ( frac {u}{U_e} big ] )dy
Answer» B. <sup>**</sup> = ( int_0^ frac {u}{U_e} big [ )1 ( frac {u}{U_e} big ] )dy
