Question:

A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.957 rad/s. You, with a mass of 67.7 k

A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.957 rad/s. You, with a mass of 67.7 kg, walk clockwise around the platform along its edge at the speed of 1.13 m/s with respect to the platform. Your 21.1-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 19.1-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 90.7 kg and radius 1.81 m. Calculate the total angular momentum of the system. Number kg. m²/s
