ities v, = 3 m/s and v (^2) = 2 m/s (Fig. 24).
As a result of collision, the bodies stick to-
gether.
Determine the amount of heat Q liber-
ated as a result of collision.
1.54. The inclined surfaces of two movable
wedges of the same mass M are smoothly
conjugated with the horizontal plane
(Fig. 25). A washer of mass m slides down the
left wedge from a height h.
To what maximum height will the washer
rise along the right wedge? Friction should
be neglected.
1.55. A symmetric block of mass m, with
a notch of hemispherical shape of radius r
Fig. 26
rests on a smooth horizontal surface near the
wall (Fig. 26). A small washer of mass m 2
slides without friction from the initial po-
sition.
Find the maximum velocity of the block.
1.56. A round box of inner diameter D con-
taining a washer of radius r lies on a table
(Fig. 27). The box is moved as a whole at a
constant velocity v directed along the lines
