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 (70.6 KiB) Viewed 37 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 20 kg and is initially running at a speed of 2 m/s tangent to the edge of the merry-go-round. The merry-go-round is a uniform disk with a mass of 80 kg and a radius of 2 m. Assume that it rotates without friction. What is the initial angular momentum L₁ of the system (kid plus merry-go-round)? 80.00 kg m²/s Computer's answer now shown above. You are correct. Your receipt no. is 161-9059 → Previous Tries What is the final angular momentum Lf of the system? 80.00 kg m²/s Computer's answer now shown above. You are correct. Previous Tries Your receipt no. is 161-8859 What is the final moment of inertia If of the system after the kid jumps on the merry-go-round? 240.0 kg m² Computer's answer now shown above. You are correct. Previous Tries Your receipt no. is 161-6329 What is the final angular velocity wf of the merry-go-round (with the kid riding)? 3 radians/s Remember that L₁= L = Iff and use information calculated in previous questions.
