Define impulse. Two blocks of masses
10g and
30g are fastened to the ends of a cord which passes over a frictionless pulley. The
10g block rests on the table. What minimum force must be applied on the
10g block to keep it on the table? What will be the tension in the cord under this condition? What will be the acceleration of the system and the tension in the cord when the force is withdrawn?
