A little girl is going on the merry-go-round for the first time, and wants her 54 kg mother to stand next to her on the ride, 2.2 m from the merry-go-round's center.
A) If her mother's speed is 3.3 m/s when the ride is in motion, what is her angular momentum around the center of the merry-go-round?
Express your answer using two significant figures.

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.)
5. Little Jay is en joying his first ride on a merry-go-round. (He is riding a stationary horse rather than one that goes up and down.) A schematic view of the merry go-round as seen from above is shown in the drawing to the right with a convenient coordinate system. A bit after the merry-go-round has started and is going around uniformly, we start our clock. Little Jays position and velocity at time t O is shown as a dot...
A 15 year old girl is riding on a playground merry-go-round, being pushed around by her friend, similar to that pictured above. The rider has a mass of 50.0 kg and a two handed grip strength of 445 N. The coefficient of friction between her and the merry-go-round is 0.100. Her friend spins her at a rate of 40 rev/min. 13. What is the frictional force, f, acting on the girl? Answer (4 points): f= 14. What is the angular...

A 2.4-m-diameter merry-go-round with a mass of 210 kg is spinning at 20 rpm. John runs around the merry-go-round at 5.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 35 kg. Part A What is the merry-go-round's angular speed, in rpm, after John jumps on? Express your answer in revolutions per minute. O AC O ? W = | rpm rpm Submit Request Answer
A 3-m-diameter merry-go-round with a mass of 270 kg is spinning at 20 rpm. John runs around the merry-go-round at 5.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John’s mass is 33 kg . What is the merry-go-round's angular speed, in rpm, after John jumps on?
A rotating merry-go-round makes one complete revolution in 4.6 s . Assume the wheel is moving with a constant angular velocity. (Figure 1) What is the linear speed of a child seated 1.4 m from the center? Express your answer to two significant figures and include the appropriate units. What is her acceleration (give components)? Enter the radial and tangential components of the acceleration using two significant figures separated by a comma.
