1.	Imagine a hard surface along xz plane to be fixed. A particle moving along the line 4x + 3y - 12 = 0 with a speed of 10m/s from the positive side of y-axis, approaches towards the plane and collides. If the coefficients of restitution be e = 0.75, then the speed of the particle after collision will besqrt(2)xm//s, then x = .........
