A playground ride consists of a disk of mass M =40 kg and radius R=1.6 m mounted on a low-friction axle (see figure below). A child of mass m=22 kg runs at speed v =2.6 m/s on a line tangential to the disk and jumps onto the outer edge of the disk. R x Your answer is incorrect. Try again. (e) The child on the disk walks inward on the disk and ends up standing at a new location a...
(4) A playground ride, known as merry-go-round, consists of a disk with a mass of 40.0 kg and a radius of 1.80 m mounted on a frictionless axle. The frictionless axle is a vertical cylinder of radius kg, and has the same rotational axis as the disk. A child with a mass of 3.50 m/s on a line tangential to the outer rim of the disk and jumps onto the outer edge of the ride while it is at rest...
Problem: A wheel consists of a disk of outer radius R = 1.6 m, with a concentric axle of inner radius r = 0.48 m. The wheel is pulled by a rope looped around the axle. The total mass of the wheel (disk + axle) is M = 12.0 kg and its moment of inertia is I = 18.4 kg m/s. A constant force F = 110 N applied horizontally at the circumference of the axle, causes the wheel to...
A 2.44-m radius playground merry-go-round has a mass of 109.8 kg and is rotating with an angular velocity of 0.71 rev/s. What is its angular velocity after a 45.8-kg child gets onto it by grabbing its outer edge? The child is initially at rest.
A playground merry-go-round(solid disk) has a mass of 120kg and a radius of 2.00m and it is rotating with an angular velocity of .500rev/s What is its angular velocity after a 20kg child gets onto it by grabbing it's outer edge? the child is initially at rest
39. A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.500 rev/s. What is its angular velocity after a 22.0-kg child gets onto it by grabbing its outer edge? The child is initially at rest.
A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.350 rev/s. What is its angular velocity (in rev/s) after a 25.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest. ______ rev/s
A 1.80 m radius playground merry-go-round has a mass of 120 kg and is rotating with an angular velocity of 0.330 rev/s. What is its angular velocity, in rev/s, after a 29.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest.
A 25-kg child running at 1.6 m/s jumps onto the outer edge of a merry-go-round of 200-kg mass and 1.8 m radius. If the merry-go-round starts from rest, what is the final angular velocity in rad/s of the child and merry-go-round? Use conservation of angular momentum and treat the merry-go-round as a solid disk.
A playground merry-go-round has a mass of 120 kg and a radius of 1.80 m and it is rotating with an angular velocity of 0.350 rev/s. What is its angular velocity (in rev/s) after a 22.0 kg child gets onto it by grabbing its outer edge? The child is initially at rest. Incorrect: Your answer is incorrect. rev/s
