Setting this equal to Eq. 89 (to find the height to which it climbs) we get
H
= ¾
d
.
Thus,
the block (momentarily) stops on the inclined ramp at the right, at a height of
H
= 0.75
d
= 0.75 ( 40 cm) = 30 cm
measured from the lowest plateau.
62. In the absence of friction, we have a simple conversion (as it moves along the
inclined ramps) of energy between the kinetic form (Eq. 71) and the potential form (Eq.
89).
Along the horizontal plateaus, however, there is friction which causes some of the
kinetic energy to dissipate in accordance with Eq. 831 (along with Eq. 62 where
μ
k
=
0.50 and
F
N
= mg
in this situation).
