- A Kid Runs Towards The Edge Of A Merry Go Round That Is Not Rotating And Jumps On The Merry Go Round Then Rotates With 1 (27.21 KiB) Viewed 40 times
A kid runs towards the edge of a merry-go-round that is not rotating and jumps on. The merry-go-round then rotates with a constant angular velocity w. Assume that the kid has a mass of 40 kg and is initially running at a speed of 4 m/s tangent to the edge of the merry-go-round. The merry-go-round is a uniform disk with a mass of 120 kg and a radius of 2 m. Assume that it rotates without friction. What is the final angular velocity wf (in radians/s) of the merry-go-round (with the kid riding)? 1.6 Do a balance of angular momentum: L Remember that L₁ = L LLkid,+Ldisk, Lkid, mkid Vkid, i*R = Ldisk,i= Idisk disk, i Idisk (1/2)*mdisk *R² L₁ = 1pWf If Ikid + Idisk = Ikid = mkid R2 Submit Answer Incorrect.
