Question

Normal 0 false false false EN-US X-NONE X-NONE 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 .

1 H = (u_y^2)/g uy = 5 m/s => v2 = 5 m/s T = (2u sinx)/g=(2u_y)/g = 1 sec S = u &times; t -1/2 a &times; t2 (as a ? in x direction) 5/4 = ux &times; 1 -1/2 &times; (0.5) &times; 1 ux = 3/2 m/sec, => v1 = 3/2 m/s Along z-axis, 5/4 = v3 &times; 1 => v3 = 5/4 m/sec. v_1/v_3 -1/v_2 =(3/2&times;4/5)-1/5 = 1
