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?
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
