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?

A small box of mass m1 is sitting on a board of mass m2 and length L.
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 team of dogs pulls a sled with a large box of food on it. The coefficient of kinetic friction between the sled and the snow is μks. a) Draw separate, carefully labeled free-body diagrams for the sled and for the box (assume the box is not strapped down, and that air resistance is negligible). b) Suppose the sled has mass ms and the box has mass mb, and that the coefficient of kinetic friction between the box and the...

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...
