A child sits on a merry-go-round at a distance of 3.0 m from its axis of rotation. The coefficient of static friction between the child and the surface of the merry-go-round is 0.6. Find the largest angular velocity (in rpm) the merry-go-round can have before the child starts to slide outward. Your solution must show a free-body diagram of the child.
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...
A child sits on a merry-go-round that has a diameter of 6.00 m. The child uses her legs to push the merry-go-round, making it go from rest to an angular speed of 15.0 rpm in a time of 37.0 s. What is the average angular acceleration aavg of the merry-go-round in units of radians per second squared (rad/s2)? avg0.042 rad/s2 What is the angular displacement Δθ of the merry-go-round, in units of radians (rad), during the time the child pushes...
A child sits on a merry‑go‑round that has a diameter of 5.00 m. The child uses her legs to push the merry‑go‑round, making it go from rest to an angular speed of 20.0 rpm in a time of 44.0 s. PART 1 What is the average angular acceleration ?avg of the merry‑go‑round in units of radians per second squared (rad/s2)? PART 2 What is the angular displacement Δ? of the merry‑go‑round, in units of radians (rad), during the time the...
5. A 3.0 m diameter merry-go-round (mass 200 kg) is spinning at 10 rpm. A child of 30.0 kg runs tangent to the merry-go-round at 2.0 m/s, in the opposite direction that it is turning, and jumps onto the outer edge. Calculate the merry-go-round's angular velocity, immediately after the child jumps on.
A brave child decides to grab on to an already spinning merry-go-round. The child is initially at rest and has a mass of 26.5 kg. The child grabs and clings to a bar that is 1.45 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 55.0 rpm to 19.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis?
A brave child decides to grab on to an already spinning merry-go-round. The child is initially at rest and has a mass of 34.5 kg. The child grabs and clings to a bar that is 1.70 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 51.0 rpm to 17.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis?
A brave child decides to grab onto an already spinning merry-go-round. The child is initially at rest and has a mass of 33.5 kg. The child grabs and clings to a bar that is 1.20 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from 47.0 rpm to 17.0 rpm. What is the moment of inertia of the merry-go-round with respect to its central axis? moment of inertia: kg. m²
