The answer to each of the questions is a single digit integer ranging from 0 to 9.A cubical box dimensional L = 5/4 metre starts moving with an acceleration a ? = 0.5 m/s2 i ^ from the state of rest. At the same time, a stone is thrown from the origin with velocity v ?=v_1 i ^+v_2 j ^-v_3 k ^ with respect to earth. Acceleration due to gravity g ? = 10 m/s2 (-j ^ ). The stone just touches the roof of box and finally falls at the diagonally opposite point then find the value of v_1/v_3 -1/v_2 .
