Two equal discs initially at rest
Webmaximum friction force isn’t enough to keep the object at rest. So it will move, and the friction force will abruptly drop to the kinetic value of µkN. (It turns out that µk is always less than or equal to µs; see Problem 4.1 for an explanation why.) The expressions in Eqs. (4.2) and (4.3) will of course break down under extreme conditions WebTwo shuffleboard discs of equal mass, one orange and the other green, are involved in a perfectly elastic collision. The green desk is initially at rest in the track of the orange disc …

WebTwo identical disks, P and Q, are initially at rest at the left end of a track, as shown above. The track has a horizontal section of length L and then curves upward at the right end. The disks are simultaneously pushed to the right from rest, with horizontal forces of equal magnitude F. Disk Q is

Two children each of mass m = 25 kg are standing on opposite sides a distance r 0 = 3.0 m from the central axis. The merry-go-round is initially at rest. A person on the ground applies a constant tangential force of F = 2.5*10 2 N at the rim of the merry go-round for a time ∆t = 10 s.
WebThe lightweight wheel on a road bike has a moment of inertia of $0.097 \mathrm{kg} \cdot \mathrm{m}^{2} .$ A mechanic, checking the alignment of the wheel, gives it a quick spin; it completes 5 rotations in 2.0 s. To bring the wheel to rest, the mechanic gently applies the disk brakes, which squeeze pads against a metal disk connected to the wheel.

When you drop a stationary disc onto a rotating one there must be a time when there is relative motion between the discs as you cannot have an infinite acceleration. If there is no friction then nothing much happens and the spinning disc carries on spinning and the other disc just sits still on top of it. rockford bowlingWeb(2 ) (1): mgh = 1 2 mv cm 2 + 1 2 1 2 mR (2 ) vcm R 2 = 3 4 mv cm 2 vcm = 4 gh 3 (2): w = 4 gh 3 R 2 • The speed at the bottom does not depend on the radius or the mass of the disk. • The speed at the bottom is less than when the disk slides down a frictionless ramp: v = 2 gh • The angular speed depends on the radius but not the mass. other games like quordle
