A ball of mass 1 kg moving with speed of 10 m/s on a smooth horizontal plane collides obliquely with another ball of same mass at rest as shown in the figure. Coefficient of restitution for the collision is 0.5. if the speed of the striking ball after the collision is \[\frac{35}{x}\]m/s, then x is
