Two blocks of mass 7.00 kg and 3.00 kg are placed in contact withone another on a smooth horizontal surface. A cosnstant horizontalforce of 15.0 N is applied to the 7.00 kg mass.
a) Find the Magnitude of the force on the 3.00 kg block.
b) Find the Magnitude of the force on the 7.00 kg blockexerted by the 3.00 kg block.
