Figure 5-23 shows the same breadbox in four situations where horizontal forces are applied. Rank the situations according to the magnitude of the box’s acceleration, greatest first

Block B in Fig. 6-31 weighs 711 N.The coefficient of static friction between block and table is 0.25; angle u is 30; assume that the cord between B and the knot is horizontal. Find the maximum weight of block A for which the system will be stationary.

Two blocks, of weights 2.0 N and 5.4 N, are connected by a massless string and slide down a 33° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.061; that between the heavier block and the plane is 0.17. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.

A 7.3 kg crate is moved rightward across a horizontal surface by a horizontal force such that it has constant velocity. If the coefficient of the kinetic friction is 0.58, calculate the magnitude of the kinetic friction force.
