Question

Two blocks are sliding to the right accross a horizontal surface, as the drawing shows. In Case A the mass of each block is 3.0 kg. In Case B the mass of block 1 (the block behind) is 6.0 kg, and the mass of black 2 is 3.0 kg. No frictional force acts on block 1 in either Case A or Case B. However, a kinectic frictional force of 5.8 N does act on block 2 in both cases and opposes the motion. For both Case A and CAse B determine (a) the megnitude of the forces with whcihthe blocks push against each other and (b) the magnitude of the acceleration of the blocks.

PROBLEM 86
87. M V-HINT The alarm at a fire station rings and an 86-kg fireman, starting
from rest, slides down a pole to the floor below (a distance of 4.0 m). Just
before landing, his speed is 1.4 m/s. What is the magnitude of the kinetic
frictional force exerted on the fireman as he slides down the pole?

88. M GO Two blocks are sliding to the right across a horizontal surface, as
the drawing shows. In Case A the mass of each block is 3.0 kg. In Case B the
mass of block 1 (the block behind) is 6.0 kg, and the mass of block 2 is 3.0 kg.
No frictional force acts on block 1 in either Case A or Case B. However, a
kinetic frictional force of 5.8 N does act on block 2 in both cases and opposes
the motion. For both Case A and Case B determine (a) the magnitude of the
forces with which the blocks push against each other and (b) the magnitude
of the acceleration of the blocks.
