A child having mass M holds her legs up as shown as she swings downward from rest at { θ }_{ 1 } . Her center of mass is located at point { G }_{ 1 } . When she is at the bottom position θ = 0°, she suddenly lets her legs come down, shifting her center of mass to position { G }_{ 2 } . Determine her speed in the upswing due to this sudden movement and the angle { θ }_{ 2 } to which she swings before momentarily coming to rest. Treat the child’s body as a particle. Given: M = 50 kg , { r }_{ 1 } = 2.80 m , g = { 9.81 m/s }^{ 2 } , { θ }_{ 1 } = 30 deg , { r }_{ 2 } = 3 m
