1) A 3-kg mass has an acceleration of (4.0i - 3.0j )m/s^2. Only two forces act on the mass. If one of the forces is ( 2.0i - 1.4j)N, what is the magnitude of the the other force ?

2) Two blocks are accelerated across a horizontal frictionless surface . Frictionless forces keep the two blocks from sliding relative to each other, and the two move with the sameacceleration. If F= 1.2 N and M = 1.0 kg, (a) draw free bodydiagram for each block and (b) determine the horizontal component (frictional force ) of the large block on the small block.

3) Two blocks connected by a string are pulled across ahorizontal surface by a force applied to one of the blocks. The coefficient of kinetic friction between the blocks and the surfaceis 0.25. (a) Draw a free-body diagram for each block. (b) If eachblock has an acceleration of 2.0 m/s^2 to the right, what is themagnitude F of the applied forces?
