I need help with exercise and practice it. PRACTICE IT Use the worked example above to help you solve this problem. A merry-go-round modeled as a disk of mass M 7.50x 101 kg and radius R 2.40 m is rotating in a horizontal plane about a frictionless vertical axle (see figure) (a) After a student with mass m 84.0 kg jumps onto the merry-go-round, the system's angular speed decreases to 2.10 rad/s. If the student walks slowly from the edge...
PRACTICE IT Use the worked example above to help you solve this problem. merry-go-round modeled as a disk of mass M 9.00 x 10 kg and radius R = 2.50 m is rotating in a horizontal plane about a frictionless vertical axle (see figure) (a) After a student with mass m = 84.0 kg jumps onto the merry-go-round, the system's angular speed decreases to 1.95 rad/s. If the student walks slowly from the edge toward the center, find the angular...
A merry-go-round modeled as a disk of mass 100 kg and radius 2.0 m is rotating around a frictionless vertical axle. After a person of mass 60 kg jumps onto the merry-go-round, the system’s angular speed decreases to 2.0 rad/s. If the person walks slowly from the edge toward the center, find the change in the system’s rotational kinetic energy caused by her movement to 0.5 m from the center.
A girl (named Mary? Get it?) stands at the outer edge of a merry-go-round at distance 2.3m from the center. The merry-go-round is rotating at 22 rpm. The girl has a mass of 30kg, and the merry-go-round has a moment of inertia of 1300kgm^2 (a) What is the moment of inertia of the girl as she rotates around the center of the merry-go-round? (b) What is the angular velocity of the merry-go-round? rad/s (c) What is the total moment of...
17. A 25.0 kg girl stands on the edge of a merry-go-round that is turning with an angular speed of 0.750 rad/s. The merry-go-round has a radius of 2.50 m and a moment of inertia of 200 kg m2. The girl walks to the center of the merry-go-round and stands there. What is the new angular speed of the merry-go-round? (Treat the girl as a point particle.)
Question (part 1 of 2) A merry-go-round rotates at the rate of 0.29 rev/s with an 79 kg man standing at a point 2.9 m from the axis of rotation. What is the new angular speed when the man walks to a point 1 m from the center? Consider the merry-go-round is a solid 44 kg cylinder of radius of 2.9 m Answer in units of rad/s. Question (part 2 of 2) What is the change in kinetic energy due...
A merry-go-round rotates at the rate of 0.38 rev/s with an 98 kg man standing at a point 1.8 m from the axis of rotation. What is the new angular speed when the man walks to a point 0 m from the center? Consider the merry-go-round is a solid 93 kg cylinder of radius of 1.8 m. Answer in units of rad/s. 024 (part 2 of 2) 10.0 points What is the change in kinetic energy due to this movement?...
