These are pretty crazy measurements for human ice skaters but anyway
w = 2 pi/7.6 = .827 radians/second
find center of mass at x from big one
x(50)=(4.6-x)(15)
50 x = 69 - 15 x
65 x = 69
x = 1.06 m from big one and 3.54 from little one
I = 50(1.06)^2 + 15(3.54)^2
= 244 kg m^2
L = ang momentum = I w
= 244 (.827)
= 202 kg m^2/s
for KE
since you already have all the numbers...
KE1 + KE2 = (.5*I1*W1^2) + (.5*I2*W2^2)
