1). A 3-kg mass has an acceleration of (4.0i - 3.0j )m/s^2. Onlytwoforces 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 horizontalfrictionlesssurface . Frictionless forces keep the two blocks fromslidingrelative 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 eachblock 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 acrossahorizontal surface by a force applied to one of the blocks.Thecoefficient of kinetic friction between the blocks and thesurfaceis 0.25. (a) Draw a free-body diagram for each block. (b) Ifeachblock has an acceleration of 2.0 m/s^2 to the right, what isthemagnitude F of the applied forces ?
