A scientist builds a device to measure the speed of a golf ball. The 0.05kg ball is fired into a 0.20kg box at the outer edge of a record turntable (a disk of mass=0.40kg and radius=0.25m). The box catches the ball and the turntable spins with an angular velocity of 1.40 rad/sec.

Calculate the following quantities:

a- moment of inertia of the turntable

b- moment of inertia of the box

c- moment of inertia of the ball (when it hits the box)

d- initial speed of the golf ball (Hint: use conservation of angular momentum)

A horizontal turntable is made from a uniform solid disk and is initially rotating with angular velocity of 7.1 rad/s about a fixed vertical axis through its center. The turntable has a radius of 0.23 m and a moment of inertia of 0.04761 kg m2 about the rotation axis. A piece of clay, initially at rest, is dropped onto the turntable and sticks to it at a distance d= 0.16 m from its center as shown in the figure. The...

A very thin 2.0-kg disk with a diameter of 80 cm is mounted horizontally to rotate freely about a central vertical axis. On the edge of the disk, sticking out a little, is a small, essentially massless, tab or "catcher." A 2.0-g wad of clay is fired at a speed of 14.0 m/s directly at the tab perpendicular to it and tangent to the disk. The clay sticks to the tab, which is initially at rest, at a distance of...

A golf club driver is swung and hits a golf ball. The driver has a shaft of length L and a head. To simplify the problem, we will neglect the mass of the driver shaft entirely. The driver head we will assume is a uniform density sphere of radius R and mass M. The golf ball is a uniform density sphere of radius r and mass  m. Initially the ball is at rest, with zero linear velocity, v → 2 i...

A) A man holds a 185-N ball in his hand, with the forearm horizontal (see the figure). He can support the ball in this position because of the flexor muscle force , which is applied perpendicular to the forearm. The forearm weighs 18.2 N and has a center of gravity as indicated. Find (a) the magnitude of and the (b) magnitude and (c) direction (as a positive angle counterclockwise from horizontal) of the force applied by the upper arm bone...
