Rotational motion
3) A horizontal circular platform can rotate around a vertical axis at its center with negligible friction. You decide to use the rotating platform to design a procedure that will allow you to determine the unknown rotational inertias of different objects, for example a bowl. You know the rotational inertia of the platform Ip. Which of the following procedures would serve your task? Comment on why. (More than one answer could be correct). Comment on the procedures that...

A 95.3 kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.69 rad/s . A monkey drops a 9.37 kg bunch of bananas vertically onto the platform. They hit the platform at 45 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 22.1 kg , drops vertically to the edge of the platform, grasps it, and continues...

A 93.9-kg horizontal circular platform rotates freely with no friction about its center at an initial angular velocity of 1.55 rad/s. A monkey drops a 9.35-kg bunch of bananas vertically onto the platform. They hit the platform at 4/5 of its radius from the center, adhere to it there, and continue to rotate with it. Then the monkey, with a mass of 21.7 kg, drops vertically to the edge of the platform, grasps it, and continues to rotate with the...

A person of mass 73 kg stands at the center of a rotating merry-go-round platform of radius 2.6 m and moment of inertia 810 kg⋅m2 . The platform rotates without friction with angular velocity 0.95 rad/s . The person walks radially to the edge of the platform. Part A Calculate the angular velocity when the person reaches the edge. Express your answer using three significant figures and include the appropriate units. For Part A, I got 0.590 rad/s. Which was...

12) A horizontal circular platform rotates counterclockwise about its axis at the rateo with a mass of 69.3 kg, walk clockwise around the platform along its edge at the speed of 1.15 m/s with respect to the platform. Your 20.7-kg po at half the platform's radius and at half your linear speed with respect to the platform. Your 17.9-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 moment of inertia of the human body about an axis through
its center of mass is important in the application of biomechanics
to sports such as diving and gymnastics. We can measure the body's
moment of inertia in a particular position while a person remains
in that position on a horizontal turntable, with the bodys center
of mass on the turntable's rotational axis. The turntable with the
person on it is then accelerated from rest by a torque that...
A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings.
A turntable has a radius of 0.80 m and a moment of inertia of 2.0 kg m2. The turntable is rotating with an angular velocity of 1.5 rad/s about a vertical axis though its center on frictionless bearings. A very small 0.40-kg ball is projected horizontally toward the turntable axis with a velocity of 3.0 m/s. The ball is caught by a very small and very light cup-shaped mechanism on the rim of the turntable (see figure). a) What is the...
