A child having a mass of 30 kg holds her legs up as shown as she swings downward from rest at Ø1 = 30°. Her center of mass is located at point G1. When she is at the bottom position Ø = 0°, she suddenly lets her legs come down, shifting her center of mass to position G2. Determine her speed in the upswing due to this sudden movement and the angle Ø2 to which she swings before momentarily coming to rest. Treat the child's body as a particle. %3D 3 m 02 2.80 m 0, = 30°) G G2 G2
