1.60. A flexible pipe of length 1 connects
two points A and B in space with an alti-
tude difference h (Fig. 31). A rope passed
through the pipe is fixed at point A.
A
Fig. 31
Determine the initial acceleration a of
the rope at the instant when it is released,
neglecting the friction between the rope
and the pipe walls.
1.61. A smooth washer impinges at a veloc-
ity v on a group of three smooth identical
blocks resting on a smooth horizontal sur-
face as shown in Fig. 32. The mass of each
block is equal to the mass of the washer.
The diameter of the washer and its height
are equal to the edge of the block.
Determine the velocities of all the bodies
after the impact.
