  1. Mechanics (^29)
    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
