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.

The left-hand end of a slender uniform rod of mass m is placed against a vertical wall. The rod is held in a horizontal position by friction at the wall and by a light wire that runs from the right-hand end of the rod to a point on the wall above the rod. The wire makes an angle θ with the rod. a)What must the magnitude of the friction force be in order for the rod to remain at rest?...

One end of a uniform meter stick is placed against a vertical wall as shown in (Figure 1). The other end is held by a lightweight cord that makes an angle with the stick. The coefficient of static friction between the end of the meter stick and the wall is 0.36. Figure 2 of 2 > Let the angle between the cord and the stick is = 18°. A block of the same weight as the meter stick is suspended...

A wooden block of mass M sits on a flat metal table which can be made to oscillate horizontally in simple harmonic motion. The coefficient of static friction between the block and table is mu. When the table oscillates, the horizontal position x of the block can be expressed as x(t) = L cos(omega t) where L is the amplitude of the oscillation and omega is the angular frequency of the oscillation. For a given amplitude, what is the maximum...

A block of mass “m” sits on a (bigger) block of mass “4m” that is on a frictionless table. The coefficients of friction between the two blocks are μs (static) and μk (kinetic). Assume that a horizontal force “F” is applied to the block on top (i.e. the smaller block with mass “m”). The force “F” is variable. The figure below is representative of this scenario. (You may use m = 10 kg, μs = 0.8, μk = 0.6, and...

2. A block with mass m is forced against a horizontal spring of 100 N/m negligible mass, compressing the spring a distance d (Figure 1). When released, the block moves on a horizontal tabletop a length L before coming to rest. The spring has a force constant k. What is the coefficient of kinetic friction between the block and the tabletop? Express your answers in terms of any or all of the variables m, d, g, L and k. B)...

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?
