Question

A cubical box dimension $L = 5 / 4 m$ start moving with an acceleration $a = 0.5 m s^{- 2}^i$ from the state of rest. At the same time, a stone is thrown from the origin with velocity $\to V = v_{1}^i + v_{2}^j - v_{3}^k$ with respect to earth. Acceleration due to gravity $\to g = 10 m s^{- 2} (-^j)$ . The stone just touches the roof of box and finally falls at the diagonally opposite point. Then:

v_{1} = \frac{3}{2}
