A merry-go-round is a common piece of playground equipment. A 3.0-m-diameter merry-go-round, which can be modeled as a disk with a mass of 210 Part A kg , is spinning at 23 rpm. John runs tangent to the merry-go-round at 4.0 m/s, in the same direction that it is turning, and jumps onto the outer edge. John's mass is 30 kg. What is the merry-go-round's angular velocity, in rpm, after John jumps on? Express your answer in revolutions per minute to two significant figures. ? W = rpm

C6M.6 A certain playground merry-go-round is essentially an iron disk of radius R and mass m. Two children, whose masses are each m, are originally sitting on opposite sides of the disk near its outer edge. The merry-go-round is turning essentially without friction around a vertical axis once every 5 s. The children then clamber toward each other until each is only R from the center. How long does it take the merry-go-round to complete a revolution now? (Hint: Model the children as particles.)
7. A 0.25 kg bullet is fired with a velocity of 200 m/s into two spheres mounted on a shaft with a vertical axis of rotation (coming out of the page) the spheres rotate horizontally. Each sphere has a mass of 0.80 kg and can be treated as a point mass. The mass of the shaft can be ignored. The bullet hits one of the spheres at the angle shown and sticks to the sphere which starts at rest. 30° Axis Of Rotation Determine the rotational inertia of the bullet/spheres system. C. d. Determine the magnitude of the angular velocity of the bullet/spheres system just after the bullet hits the sphere. 0.50 m
A horizontal circular platform rotates counterclockwise about its axis at the rate of 0.827 rad/s. You, with a mass of 74.5 kg,walk clockwise around the platform along its edge at the speed of 1.13 m/s with respect to the platform. Your 20.5 kg poodle also walks clockwise around the platform, but along a circle at half the platform's radius and at half your linear speed with respect to the platform. Your 18.7 kg mutt, on the other hand, sits still on the platform at a position that is 3/4 of the platform's radius from the center. Model the platform as a uniform disk with mass 90.9 kg and radius 1.87 m. Calculate the total angular momentum of the system.
You and a friend from high school are off-roading through Ocala National Forest in your friend’s Jeep (mass of 1800 kg), when a Florida panther runs onto the path. You swerve to miss the panther, but slide into a muddy ditch and get stuck. Luckily, your friend has a winch on their Jeep, which you connect to a tree as shown in the figure. The ground between the Jeep and the tree has a steady slope with an angle of 5 degrees, and the coefficient of kinetic friction between the muddy ground and the rubber tires is 0.15. Consider that the winch is being used to pull the Jeep out of the ditch at a steady speed, while for part c the speed of the Jeep can change. a. Is the mechanical energy of the Jeep conserved? Give two different reasons why or why not. b. What is the work done by the normal force as the jeep is pulled up the slope? c. Assume that the Jeep is initially at rest, when you start the winch operating at its maximum power output of 6.6 horsepower (about 5000 W). After 2 seconds,…

At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 2.72 m/s, and an 82.0-kg person feels a 276-N force pressing against his back. What is the radius of a chamber?
