14:43 4H7Ell ... @50%Gju piazzacom 2/2 (10) [5 points] Since throwing blocks results in not-so-exciting rotation, the child stands in the center of the platform (on the axis of rotation ) and has some friends spin the merrygoround from the rim. The child's friends take off leaving them spinning once every 0.9 seconds. Now the child is having too much rotational enjoyment! Being a physics prodigy (despite the poor block- throwing experiment), they know that angular momentum is conserved for a system with no external torques, and walk out to the edge of the merry-goround, which is a distance R = 1.5 meters from the center. (a) Using the numerical parameters from the previous question, find the new slower rotation period. (b) What is their tangential velocity? Do you think the child can jump off (in the direction opposite to rotation) and hit the ground with zero speed
