A small box of mass m1 is sitting on a board of mass
m2 and length L. The board rests on a frictionless
horizontal surface. The coefficient of static friction between the
board and the box is μs. The coefficient of kinetic
friction between the board and the box is, as usual, less than
μs.Throughout the problem, use g for the magnitude of the acceleration
due to gravity. In the hints, use Ff for the magnitude
of the friction force...
A box of mass 2kg is sitting on top of a sled of mass 5kg, which is resting on top of a frictionless surface (ice). If you pull on the sled with a force of 35N, how large does the coefficient of static friction between the box and the sled have to be, in order for the box to move with the sled?
In the figure, a slab of mass m1 = 40 kg
rests on a frictionless floor, and a block of mass
m2 = 8 kg rests on top of the slab. Between
block and slab, the coefficient of static friction is 0.60, and the
coefficient of kinetic friction is 0.40. A horizontal force F of
magnitude 105 N begins to pull directly on the block, as shown. In
unit-vector notation, what are the resulting accelerations of

frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at

A box is sitting on a board. One side of the board is raised until the box starts sliding. When it starts sliding the angle of the board from horizontal is 36.869898 degree. The board is then held at that angle. The acceleration of the box down the board is 1.96m/s^2. a) What is the coefficient of static friction between the box and the board?

A block of mass m1 sits on a block of mass m2. Block m2 rests on a frictionless surface. The coefficient of static friction between block m1and m2 is µ.
