The coefficient of static friction is 0.60 between the two blocks in figure. The coefficient of kinetic friction between the lower block and the floor is 0.20. Force causes both blocks to cross a distance of 5.0 m, starting from rest.What is the least amount of time in which this motion can be completed without the top block sliding on the lower block?

Two blocks with masses of 46.4 kg and 24.9 kg are stacked on a table with the heavier block on top. The coefficient of static friction is 0.630 between the two blocks and 0.290 between the bottom block and the table. A horizontal force is slowly applied to the top block until one of the blocks moves. The acceleration of gravity is 9.81 m/s2.

a) What is the friction force between the blocks? Answer in units of N.

b) What is the friction force between the lower block and the table? Answer in units of N.

c) What minimum value for the coefficient of static friction between the masses and the table would cause the slippage to first happen between the blocks?

 Review. A light spring of force constant 3.85N/m is compressed by 8.00 cm and held between a 0.250 kg block on the left and a 0.500-kg block on the right. Both blocks are at rest on a hrizontal surface. The blocks are released simultaneously so that the spring tends to push them apart. Find the maximum velocity each block attains if the coefficient of kinetic friction between each block and the surface is

(a) 0, (b) 0.110, and (c) 0.462. 

Assume the coefficient of static friction is greater than the coefficient friction in every case.
