We know the heart shaped object has a moment of inertia of I =
0.5kgm^2. Calculate the change in angular momentum (L) of the
object in 5s (~L=~τ∆t). This question deals with angular momentum
conservation. Two girls of mass 100 kg each stand at the center of
a rotating merry-go-round (MGR) in the shape of a disk of radius 1
m and mass 10 kg. The platform rotates atω= 0.40 rad/s. Let’s call
this configuration instant A.

A carnival merry-go-round has a large disk-shaped platform of mass 120 kg that can rotate about a center axle. A 60- kg student stands at rest at the edge of the platform 4.0 m from its center. The platform is also at rest. The student starts running clockwise around the edge of the platform and attains a speed of 2.4 m/s relative to the ground. A) Determine the rotational velocity of the platform. B) Determine the change of kinetic energy...

Please answer that question ASAP
1. Consider a disc and hoop both of the same mass M, radius R and thickness I. a) Explain why one of these objects has a larger moment of inertia (about an axis through the center of mass and perpendicular to the plane of the object) than the other. What effect does the thickness I have on the rotational inertia? b) Explain how the rotational inertia of the disc may be obtained by adding the...

59 The figure shows a tabletop experiment that can be used to determine an unknown moment of inertia. A rotating platform of radius R has a string wrapped around it. The string is threaded over a pulley and down to a hanging weight of mass m. The mass is released from rest, and its downward acceleration a (a > 0) is measured. Find the total moment of inertia I of the platform plus the object sitting on top of it....
