Energy of a Bullet Dissipated by Plywood. As part of a criminal investigation, you need to determine how much of a bullet's energy is dissipated by a 0.500-inch piece of plywood. You construct a device that consists of three disks that are separated by a distance d = 0.850 m and rotate on a common axis. The bullet is fired through the first disk (a few inches above its center), which is composed of a light plastic that has a negligible effect on the speed of the bullet. The bullet then passes through the second disk, which is composed of 0.500-inch plywood. Finally, the bullet strikes the third disk, where it becomes embedded. The disks rotate with an angular velocity of w = 86.0 rad/s. The angular displacement between holes in the first and second disks is A012 = 0.269 rad, and the angular displacement between the holes in the second and third disks is A023 = 0.286 rad. If the mass of the bullet is 12.0 g, find (a) the initial speed of the bullet and (b) the energy dissipated by the 0.50-inch plywood. (a) Number i (b) Number Units Units

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

Energy of a Bullet Dissipated by Plywood. As part of a criminal investigation, you need to determine how much of a bullet's energy is
dissipated by a 0.500-inch piece of plywood. You construct a device that consists of three disks that are separated by a distance d =
0.850 m and rotate on a common axis. The bullet is fired through the first disk (a few inches above its center), which is composed of a
light plastic that has a negligible effect on the speed of the bullet. The bullet then passes through the second disk, which is composed of
0.500-inch plywood. Finally, the bullet strikes the third disk, where it becomes embedded. The disks rotate with an angular velocity of
w = 86.0 rad/s. The angular displacement between holes in the first and second disks is A012 = 0.269 rad, and the angular displacement
between the
holes in the second and third disks is A023 = 0.286 rad.
If the mass of the bullet is 12.0 g, find (a) the initial speed of the bullet and (b) the energy dissipated by the 0.50-inch plywood.

A bowling ball (which we can regard as a uniform sphere) has a mass of 7.26 kg and a radius of 0.216 m. A baseball has a mass of 0.145 kg. If you connect these two balls with a lightweight rod, what must be the distance between the center of the bowling ball and the center of the baseball so that the system of the two balls and the rod will balance at the point where the rod touches the surface of the bowling ball?
a small 0.383 kg block slides down a frictionless surface through height h = 0.752 m and then sticks to a uniform vertical rod of mass M = 0.766 kg and length d = 2.34 m. The rod pivots about point O through angle θ before momentarily stopping. Find θ.
During your winter snowboard run at park city you decide to try a back flip during the movement. When you very first take off on the jump you are moving at 5.4 rad/sec. As you get into the air you tuck to try and complete the trick, this is to ensure that you can decrease your radius of gyration from .51 to .27 during the flip in the air. To make the jump cooler you have a gopro on your helmet that is a distance of 0.25 from your COG where you are rotating. What is the linear velocity of that GoPro during the rotation of your flip. ?
A gymnast swings on the high bar as shown in the figure. Starting from rest directly over the bar, he swings around the bar while keeping his arms and legs outstretched. Treating the gymnast as though his entire mass were concentrated at a point y=0.87 m from the bar, determine his speed as he passes under the bar at position A. Note that you do not need know his mass to solve this problem. It is asking for the units in m/s
Let's consider the three atoms composing the molecule now have different masses and coordinate, while the axis of rotation is still z axis that is perpendicular to the xy plane. The first atom has a mass of 142.54 kg, with x coordinate at 3 m and y coordinate at 6 m. The second atom has a mass of 82.55 kg, with x coordinate at 1 m and y coordinate at 6 m. The third atom has a mass of 8 kg, with x coordinate at 5 m and y coordinate at 9 m. What is the moment of inertia in unit of kg m2 with respect to the x axis?
An asteroid has a mass of m = 2.6 x 106 kg and is approaching Earth. When the asteroid is exactly 3 radii away from the Earth's centre, it's speed relative to the Earth's centre is u = 8.7 x 103 ms-1. The asteroid then falls to the Earth's surface, but remains intact without dissipating any energy as it passes through the Earth's atmosphere. If the rotation of the asteroid and the Earth is ignored, what is the kinetic energy of the asteroid just before it hits the ground?
