WebA playground merry-go-round of radius R = 2.10 m has a moment of inertia of I... A playground merry-go-round of radius R = 2.10 m has a moment of inertia of I = 260 kgm2 and is rotating at 11.0 rev/min about a frictionless vertical axis. Facing the axle, a 23.0 kg child hops on to the merry-go-round and manages to sit down on its edge. Web1 apr. 2010 · Homework Statement. A 31.0 kg child runs with a speed of 2.80 m/s tangential to the rim of a stationary merry-go-round . The merry-go-round has a moment of inertia of 520 kg\cdot m^2 and a radius of 2.51 m. When the child jumps onto the merry-go-round, the entire system begins to rotate. A) Calculate the initial kinetic energy of the system.

WebQuestion: A 4.5-m radius playground merry-go-round with a moment of inertia of 1800 kg m2 is rotating freely with an angular speed of 1.0 rads. Two people, each having a mass … WebWe expect the angular acceleration for the system to be less in this part, because the moment of inertia is greater when the child is on the merry-go-round. To find the total moment of inertia I I size 12{I} {} , we first find the child’s moment of inertia I c I c size 12{I rSub { size 8{c} } } {} by considering the child to be equivalent to a point mass at a … dresser chocolate brown

WebPerson on a Merry-Go-Round. A 25-kg child stands at a distance [latex] r=1.0\,\text{m} [/latex] from the axis of a rotating merry-go-round (). The merry-go-round can be approximated as a uniform solid disk with a mass of 500 kg and a radius of 2.0 m. Find the moment of inertia of this system. Web18 apr. 2005 · The initial angular momentum (mvr) equals the final angular momentum. You'll need to find the rotational inertia (I) of the system (merry-go-round + runner). The angular momentum is the key. You are right about that. I am assuming the runner is approaching the merry-go-round on a tagent line. His angular velocity at the moment of … Web7 dec. 2015 · Playground Physics: Determining the Moment ofInertia of a Merry - Go - Round Stephen Van Hook, Adam Lark † , Jeff Hodges, Eric Celebrezze, and … dresser clark
