See question below Q11.7.a Child runs and jumps on playground merry-go- round. For the system of the child + disk (excluding the axle and the Earth), 1. K, P, and L do not change which statement is true . Pand L do not change from just before to just 3. L does not change after impact? Af 4. K and F do not change 5. K and L do not change K is total kinetic energy is total linear momentum L is total angular momentum about the center of mass. Motter & Interactions 4e A. 1 B.2 D. 4 E. 5 Type here to search DlI dx PrtScn FT F2 F3 F4 FS F6 FT Solution Total angular momentum about the axis passing through center of mass of the system won\'t change between before and after the jump because if we consider child and disc as a system then, the torque developed due to impulsive force would be an internal torque with respect to the axis passing through center of mass hence we do not have any external torque acting on the system therefore angular momentum remains conserved, and we can\'t say linear momentum is conserved because rotating merry go round is a non inertial frame of reference and the child is acted upon by centrifugal force. .
