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...

Thanks so much for the help! Please show all work. A uniform solid disk with radius 9 cm has mass 0.5 kg (moment of inertia I = ½MR2). A constant force 12 N is applied as shown. At the instant shown, the angular velocity of the disk is 40 radians/s in the −z direction (where +x is to the right, +y is up, and +z is out of the page, toward you). The length of the string d is 13...

A. 0.6 kgm2 B. 2.4 kgm2 O C.1.2 kgm2 19. Click Go. what is the angular acceleration of the platform? Calculate it using Newton's second law for rotational motion: torque = (moment of inertia) (angular acceleration) and then verify with the simulation. A. 1.6 rad/s2 B. 1 rad/s C. 0.83 rad/s2 20. Decrease the radius of the platform to 3 m (mass stays the same). What happens to the moment of inertia of the platform?...

10. Tim attaches the string of a 0.10 kg yo-yo to his finger and releases the yo-yo from rest. As the yo-yo spins down, Tim keeps his finger motionless, which allows the yo-yo to be treated the same as a freely rolling object. After the yo-yo drops a distance of 0.90 m, it has a translational speed of 4.0 m/s and an...

1) A uniform 14 kg cylinder turns on a horizontal axis with a
significant amount of friction. The cylinder has a radius of 0.030
m and a thickness of 0.080 m. It is initially at rest. Then a force
of 70 N is applied at a 37 angle for 2.0 s, as indicated in the
figure, and the cylinder accelerates. After a time of 2.0 s the
force is reduced to 24 N, and then the cylinder continues to spin...
