In this video we are going to solve a question on Newton's Law of motion. This time a system of two blocks, but they are moving in different directions.
Question 2
A 4 kg block on a horizontal, rough surface is connected to a 8 kg block by a light inextensible string that passes over a frictionless pulley as shown below. The coefficient of kinetic (dynamic)friction between the block of 4 kg and the surface is 0,6.
SEE PICTURE IN THE THUMBNAIL. 👀👀👀
2.1.Draw a free-body diagram of all the forces acting on both blocks.
2.2. Write down Newton’s second law of motion in words.
2.3. Calculate the acceleration of the system.
2.4. Calculate the magnitude of the tension in the string.
2.5. Calculate the magnitude of the frictional force that acts on the 4 kg block.
