A small 4-lb collar C can slide freely on a thin ring of weight 6 lb and radius 10 in. The ring is welded to a short vertical shaft, which can rotate freely in a fixed bearing. Initially the ring has an angular velocity of 35 rad/s and the collar is at the top of the ring (θ = 0) when it is given a slight nudge. Neglecting the effect of friction, determine a) the angular velocity of the ring as a function of θ. (1 point) b) the velocity of the collar relative to the ring as a function of θ. (1 point)

13.C1 A 12-lb collar is attached to a spring anchored at point C and can slide on a frictionless rod forming an angle of 30° with the vertical. The spring is of constant k and is unstretched when the collar is at A. Knowing that the collar is released from rest at A, use computational software to determine the velocity of the collar at point B for values of k from 0.1 to 2.0 lb/in 20 in. 20 in. 30...
Required information NOTE: This is a multi-part question. Once an answer is submitted, you ll be unable to return to this part A 1-kg collar can slide on a horizontal rod, which is free to rotate about a vertical shaft. The collar is initially held at A by a cord attached to the shaft. A spring of constant 30 N/m is attached to the collar and to the shaft and is undeformed when the collar is at A As the...
A small 0.37 g bug stands at one end of a thin uniform bar that is initially at rest on a smooth horizontal table. The other end of the bar pivots about a nail driven into the table and can rotate freely, without friction. The bar has mass 1.1g and is 2.89 cm in length. The bug jumps off in the horizontal direction, perpendicular to the bar, with a speed of 4.3 cm/s relative to the table. What is the...
Question 6 (1 point) L2 L2 ?- k L1 A collar can slide without friction along a horizontal rod and is in equilibrium at A when it is pushed to the right and released from rest. Given weight of collar: 5 lbs pushed 3 inch to right L1 = 7 in L2 - 10 in k = 3000 lb/in Find max velocity of the collar (ft/s) 70.34 80.424 92.986 119.3 138.226 164.07 226.23
Problem 14.47) Disks A, B, C, and D can ślide freely on a frictionless horizontal surface. Disks B, C, and D are connected by light rods and are at rest in the position shown when disk B is struck squarely by disk A which is moving to the right with a velocity vo 12 m/s. The masses of the disks are m,-m,-mc - 7.5 kg, and m 15 kg. Knowing that after impact disks A and B are bound togetherV)...
Help Save &Exit Submit Check my work Three small identical spheres A-8, and C, which can slide on a horizontal, frictionless surface, are attached to three strings, 0.25 ft long, which are tied to a ring G. Initially the spheres rotate counterclockwise about the ring with a relative velocity of 2.5 ft/s and the ring moves along the x axis with a velocity vo (1.25 f/s)i. Suddenly the ring breaks and the three spheres move freely in the xy plane...
A small electrically charged bead with the mass m and charge Q can slide on a circular insulating string without friction. The radius of the circle is r. A point-like electric dipole is at the center of the circle with the dipole moment P lying in the plane of the circle. Initially the bead is at an angle θ = 플 +6, where δ is infinitely small, as shown schematically in the figure below. Figure 3: Bead on a string...
Work out the highlighted questions (3-6) clearly and with units, please. Thanks! 4/5 a the minimum kinetic energy at the apping point? (C) Use conservation of energy to determine the minimum angular velocity of the block just after the collision, (d) then use conservation of angular momentum during the collision to find the initial speed of the bullet vo. (Hint: Ignore the mass of the bullet after the collision. The moment of inertia of the cube about its bottom-right edge...
