A mass MI slides on a 45° inclined plane of height HỊ 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. The acceleration of M2 downward is 1.43 m/s^2 and Box 2 will strike the ground at
