15) A merry-go-round makes one complete turn every 12s. If a 45 kg child sits on the horizontal floor of the merry-go-round 3 m from the center, a) Sketch the problem. Identify the forces on the child. Show the direction of the acceleration of the child. b) Draw a force vector diagram. c) What is the speed of the child? d) What �s the child?s acceleration? e) What is the horizontal force of friction that acts on the child (provide...
Tommy sits on a merry-go-round. While the merry-go-round is spinning, Tommy can sit in the center without holding on, but as he moves towards the outside he must hold on so he will not fly off. Explain why he feels like he will fly off? Show all your work, including formulas and units.
1. (10 pts) A merry-go-round is spinning as indicated in the figure. The merry-go-round is slowing down. What are the direction and units of the angular momentum, angular velocity, angular acceleration? What is the direction and units of the centripetal acceleration of someone sitting on the outside? How would you find how long the merry-go-round takes to stop? Direction & Units of Angular Momentum: Direction & Units of Angular Velocity: helly Butward Up + Counterclockwise Direction & Units of Angular...
A merry-go-round is spinning around a frictionless axle at its center with a person standing at the edge. The person then begins to walk toward the center. Will the merry-go-round spin faster or slower as a result? Explain your answer.

A child sits on a merry‑go‑round that has a diameter of 4.00 m. The child uses her legs to push the merry‑go‑round, making it go from rest to an angular speed of 19.0 rpm in a time of 47.0 s. What is the average angular acceleration ?avg of the merry‑go‑round in units of radians per second squared (rad/s2)? ?avg= What is the angular displacement Δ? of the merry‑go‑round, in units of radians (rad), during the time the child pushes the...
