1. Three blocks with masses of 5 kg, 3 kg and 2 kg respectively is being pushed by an external force of
   150 N. Find the force exerted by block 2 to block 3.

                                             a




           Fext = 150 N
                                        m1
                                                       m2
                                                            m3




2. Block of m1 = 3 kg which located on the rough surface with µs = 0.5 and µk = 0.2, is pulled out by an
   external force of 150 N, and the other block of m2 = 5 kg is suspended with a string that connected
   to block m1 via a pulley. Find the tension of the string.

              150 N
                              m1




                                                  m2




3. An external force of 100 N is exerted on a block of 5 kg which is on an inclined plane with angle of
   370. Find the acceleration of the block.



                                   kg
                              =5
                          m
                  0N
             10




                   37 0




4. Find the friction force between block m1 and m2 if the block m1 accelerated 6.25 m/s2. (m1 = 4 kg and
   m2 = 2 kg).



                              m2
                                                 100 N
                                   m1
