Must show all work!!!! A Playground merry-go-rond has a radius of r=3.0m and mass 120kg it is initally spinning at wo=.80 rad/s when a child of mass m=20kg initially still at the center of the merry go round crawls to the rim and stops moving with respect to the merry go round. the moment of intertial of the merry go round is 1/2mr^2
A.) calculate the angular momentum of the merry go round and child system when the child is at the center of the merry go round?
B.) calculate th angular velocity of the merry go round and child system when the child reaches the rim?
A 11.0g bullet is fired horizontally into a 103g wooden block that is firstly at rest on a frictionless horizontal surface and connected to a spring of constant 154N/m. The bullet becomes embedded in block. If the bullet-block system compresses the s..
