    How do we calculate a block M1,mass 8kg lies on a rough incline.it is connected to another black M2 which also has a mass of 8 kg by means of a light inexpensive string ,over a light frictionless pulley.The coefficient of kinetic friction between M1 and the incline is 0.2. In the setting M2 moves downwards T is the tension is the string.

    • @MlungisiNkosi

      Because the variables changed. If the system was stationary and now starts moving - the force, acceleration and tension change.

    sir if they say acceleration needs to be calculated '"relative to the x-axis" do they mean thst we should consider forces on the x-axis only regardless angles between the forces?

    • @MlungisiNkosi
      @MlungisiNkosi  2 ปีที่แล้ว +1

      Yes that’s what it means. You might need to resolve any for acting an angle into its horizontal or x- component
