Homework Statement

The 1.0 kg block is tied to the wall with a rope. It sits on the top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is 0.40.

a) what is the tension of the rope holding the 1.0 kg block to the wall?

b) What is the acceleration of the 2.0 kg block?

Homework Equations

Newton's third law, kinematics

The Attempt at a Solution

I tried to find the tension by using Newton's third law
