Question

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 ?k = 0.400.

1.What is the tension in the rope holding the 1.0 kg block to the wall?

2.What is the acceleration of the 2.0 kg block?

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 ?k = 0.400. What is the tension in the rope holding the 1.0 kg block to the wall? What is the acceleration of the 2.0 kg block?

Explanation / Answer

You got the first part right. Now you need to consider another equation ... one that describes force and acceleration ... F = ma, right?

You established that the tension holding the 1.0 kg block to the wall is 4.70 N, which is your normal force (1.0 kg * 9.8 m/s
