solve the problem

As shown in the figure, a 10-kg block on a perfectly smooth horizontal table is connected by a horizontal string to a 63-kg block that is hanging over the edge of the table. What is the magnitude of the acceleration of the 10-kg block when the other block is gently released? Table () 8.1 mi/s* 8.5 m/s? (7.5 mi/s* ) 9.0 m/s
