2.16 A mass M₁ slides on a 45° inclined plane of height H as shown in Fig. 2-14.
It is connected by a flexible cord of negligible mass over a small pulley (neglect its
mass) to an equal mass M₂ hanging vertically as shown. The length of the cord
is such that the masses can be held at rest both at height H/2. The dimensions
of the masses and the pulley are negligible compared to H. At time t=0 the
two masses are released.
