A movable plank of mass m is placed on a horizontal surface. A solid ball of mass m and radius R is released from the incline as shown in the figure. Friction on the plank is sufficient to prevent slipping between the plank and the ball while there is no friction between the plank and the ground. The ball will leave the incline horizontally with velocity sqrt((x)/(9)"gh") where 'x' is

1.	A movable plank of mass m is placed on a horizontal surface. A solid ball of mass m and radius R is released from the incline as shown in the figure. Friction on the plank is sufficient to prevent slipping between the plank and the ball while there is no friction between the plank and the ground. The ball will leave the incline horizontally with velocity sqrt((x)/(9)"gh") where 'x' is
