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.

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.

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.
