The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is µk = 0.40. What is the tension in the rope holding the 1.0 kg block to the wall?
Answer “The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N”.
Friction Force:
The friction force can be described as a force that acts opposite to the motion in the system. This is done by using the friction coefficient, or the coefficient of friction. The friction coefficient, or the coefficient of friction, is smaller than the friction force.
Answer and Explanation:
Given data:
- The mass of the upper block is m1 = 1.0kg
- The mass of the lower block is m2 = 2.0kg
- The tension force acting on the lower block is F = 20N.
- The coefficient of kinetic friction is μk=0.40.
This is the expression that describes the tension of the rope attached at the wall using an equilibrium condition:

So, g refers to the gravitational acceleration and its standard value is 9,81 m/s2
Substitute these values for the expression above:

The tension of the rope that is attached to the wall is 4N
Last words
Above is the solution of “The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N.“. If you have good solutions or comments, please leave a message.
