As the drawing illustrates, two disks with masses m₁ and m2 are moving horizontally to the right at a speed of vo. They are on an airhockey table, which supports them with an essentially frictionless cushion of air. They move as a unit, with a compressed spring between them, which has a negligible mass. Then the spring is released and allowed to push the disks outward. Consider the situation where disk 1 comes to a momentary halt shortly after the spring is released. Assuming that m₁ = 1.5 kg, m₂ = 2.5 kg, and vo= +5.3 m/s, find the velocity of disk 2 at that moment.

A bullet of mass m and speed v passes completely through a pendulum bob of mass M as shown in the figure below. The bullet emerges with a speed of v/2. The pendulum bob is suspended by a stiff rod of length L and negligible mass. What is the minimum value of v such that the bob will barely swing through a complete vertical circle? (Use any variable or symbol stated above along with the following as necessary: g.) 2M√5gL V = m 732 M v/2
A physical pendulum consists of a vertical board of of mass 6.11 kg, length 176 cm, and width 11 cm hanging from a horizontal, frictionless axle. A bullet of mass 145 g and a purely horizontal speed v impacts the pendulum at the bottom edge of the board. The board then makes a complete circle. (a) If the bullet embedded itself in the board, what is the minimum speed the bullet could have to make this so? 151.2 m/s (b) If the bullet passed through the board, reducing its speed by 1/6 its original value, what is the minimum speed of the bullet? 190 m/s X (c) If the bullet is made of rubber and rebounds elastically, what is the minimum speed the bullet could have? (d) What is the rebound speed of the bullet?
Ballistic pendulum: A projectile of mass m = 1 kg is fired with an initial speed v0 = 20 m/s at the bob of a pendulum with radius R = 3 m. The bob has mass M = 4 kg and is suspended by a rod of negligible mass. After the collision the projectile and bob stick together and swing at speed vf through an arc reaching height h and stop. (assume g=10 m/s2) (1) What is the speed vf just after the collision ? (2) What is the total kinetic energy for projectile and bob together just after the collision?

A rod of mass M = 3.25 kg and length L can rotate about a hinge at its left end and is initially at rest. A putty ball of mass m = 65 g, moving with speed v = 5.25 m/s, strikes the rod at angle θ = 51° from the normal at a distance D = 2/3 L, where L = 1.3 m, from the point of rotation and sticks to the rod after the collision. 1. What is the angular speed ωf of the system immediately after the collision, in radians per second?
A person picks up an iron ball on a rope and starts to spin it around them. The person does 500 J of work to get the mass spinning. While spinning, the person steps onto ice (take friction out of the equation). The result is both the mass and the person are spinning around the same point in space (the mass is circling faster on a larger radius and the man is circling slower on a smaller radius). There is a point between the masses that is stationary. The iron ball has a mass of m = 10 kg. The person has a mass of M = 80 kg. 3 vb Point that masses rotate around M Vp When the person lets go of the rope, how fast will the person move and how fast will the ball move?
The figure shows multiple solid disks with uniform mass distribution that are spinning about its center. The mass of the disks are the same, but they have different radii, as shown. Rank the disks by the amount of energy needed to spin the disk so that the outer edge of the disk has linear velocity v, from greatest to least. Explain your reasoning. A B с
Apollo and Artemis are playing on the teeter‑totter in their school's playground. They both have approximately the same mass. They are sitting on either side of the teeter‑totter at about the same distance from the teeter‑totter's pivot point. The teeter‑totter is going up and down and they are having a great time! Mercury, the new kid in school, wanders by. Since they are very friendly kids, Apollo and Artemis ask Mercury to join them. Mercury joins Apollo on his side of the teeter‑totter and sits next to him. What should Artemis do in order to keep the fun going? 1)Move farther from the teeter‑totter's pivot point in order to balance out the new smaller torque provided by Mercury and Apollo. 2)Move closer to the teeter‑totter's pivot point in order to balance out the new larger torque provided by Mercury and Apollo. 3)Move farther from the teeter‑totter's pivot point in order to balance out the new larger torque provided by Mercury and Apollo. 4)Move closer to the…
