Classical Mechanics  0 pts pending A wedge-shaped block of mass
M rests on a smooth horizontal table.A small block of mass m is
placed on its upper surface, which isalso smooth and inclined at
an angle α to the horizontal. Thesystem is released from rest.
Write down the horizontal componentof momentum, and the kinetic
energy of the system, in terms of thevelocity v of the wedge and
the velocity u of the small blockrelative to it. Using
conservation of momentum and the equation forthe rate of change
of kinetic energy, find the accelerations of theblocks.  du/dt =
(M + m)gsinα/(M + msin2x) dv/dt = mgsinαcosα/(M + msin2x)
