A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.957 rad/s. You, with a mass of 65.3 kg, walk clockwise around the platform along its edge at the speed of 1.13 m/s with respect to the platform. Your 20.7 kg poodle also walks clockwise around the platform, but along a circle at half the platform's radius and at half your linear speed with respect to the platform. Your 18.3 kg mutt, on the other hand, sits still on the platform at a position that is 3/4 of the platform's radius from the center. Model the platform as a uniform disk with mass 90.9 kg and radius 1.97 m. Calculate the total angular momentum Ltot of the system. Ltot = kg-m²/s
