The speed of a moving bullet can be determined by allowing the
bullet to pass through two rotating paper disks mounted a distance
70 cm apart on the same axle. From the angular displacement 37.5 ◦
of the two bullet holes in the disks and the rotational speed 610
rev/min of the disks, we can determine the speed of the bullet.

The speed of a moving bullet can be determined by allowing the
bullet to pass through two rotating paper disks mounted a distance
d apart on the same axle. From the angular displacement of the two bullet holes in the disks
and the rotational speed of the disks, we can determine the speed v
of the bullet. Find the bullet speed for the following data: d =
80, = 900 rev/min, and = 31 degrees.

The figure shows a device that can be used to measure the speed of a bullet. The device consists of two rotating disks, separated by a distance of d = 0.756 m, and rotating with an angular speed of 86.1 rad/s. The bullet first passes through the left disk and then through the right disk. It is found that the angular displacement between the two bullet holes is = 0.177 rad. From these data, determine the speed of the bullet....
A bullet is shot through two cardboard disks attached a distance D apart to a shaft turning with a rotational period T, as shown.
A bullet is shot through two cardboard disks attached a distance D apart to a shaft turning with a rotational period T, as shown. Derive a formula for the bullet speed u in terms of D, T, and a measured angle e between the position of the hole in the first disk and that of the hole in the second. If required, use r, not its numeric equivalent. Both of the holes lie at the same radial distance from the shaft....

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.00 kg m about its central axis, is set spinning counterclockwise at 550 rev/min. The second disk, with rotational inertia 6.40 kg m about its central axis, is set spinning counterclockwise at 800 rev/min. They then couple together. (a) What is their angular speed after coupling?...

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

Q20 (15 points): A bullet of mass m X102 kg is moving with a speed of 100 m/s when it collides with a rod of mass mR 5 kg and length L m (shown in the figure). The rod is initially at rest, in a vertical position, and pivots about an axis going through its center of mass. The bullet imbeds itself in the rod at a distance L/4 from the pivot point. As a result, the bullet-rod system starts...

Review Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0° (above the horizontal) travels a horizontal distance of d 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s for the free-fall acceleration. Find the height y, from which the rock was launched. Express your answer in meters to three significant figures.
