A small coin (mass m) is placed on a disc that is rotating at a constant angular speed ω. You know that the coefficient of static friction between the coin and the disc is μ. Determine the largest distance r from the axis of rotation that the coin can be placed so that it will not fly off the rotating disc.

Chapter D3, Problem D3/067 The small object is placed on the inner surface of the conical dish at the radius shown. If the coefficient of static friction between the object and the conical surface is 0.17, for what range of angular velocities w about the vertical axis will the block remain on the dish without slipping?

A small coin (mass m) is placed on a disc that is rotating at a constant angular speed ω. You know that the coefficient of static friction between the coin and the disc is μ. Determine the largest distance r from the axis of rotation that the coin can be placed so that it will not fly off the rotating disc. Reflection suggestion: Does the largest distance get bigger or smaller if you increase ω?

A block of mass m is placed against the vertical front of a cart
of mass M as shown in the figure. (Figure 1)
Assume that the cart is free to roll without friction and that
the coefficient of static friction between the block and the cart
is μs. Derive an expression for the minimum
horizontal force that must be applied to the block in order to keep
it from falling to the ground.

A small mass m slides without friction along the looped apparatus shown in Fig
A small mass m slides without friction along the looped apparatus shown in Fig. 6-39. If the object is to remain on the track, even at the top of the circle (whose radius is r), from what minimum height h must it be released? (Answer in terms of r.)

mi 13) A block with mass m = 5.00 kg is placed on an inclined plane with slope of a = 30.0° and is connected to a hanging block with mass m2 = 3.00 kg by a cord passing over a small, frictionless pulley as shown in the figure to the right. The coefficient of static friction is 0.333, and the coefficient of kinetic friction is 0.150. What is the magnitude and direction of the friction force on block mı?

A box with mass m is placed on top of a box with mass 2m as
shown in the figure. An external force F (t) = αt, where α is a
positive constant, acts on the bottom block and causes it to
accelerate from rest at t = 0. The two blocks have coefficient of
static friction μ between them, and the bottom box slides on a
frictionless surface. At what time will the top block begin to
slide relative...

A small block of mass m is at rest on a table. The coefficient of friction between the block and the table is mu. (The coefficient of static friction is equal to the coefficient of kinetic friction in this problem.) A horizontal force is applied at t = 0 which has magnitude beta t where beta is a known constant. Find the block's velocity as a function of time. Free Body Diagrams (If appropriate). Law or Definition
