Applying Newton's 2nd Law Submit My Answers Give Up Learning Goal: To leam a systematic approach to solving Newton's 2nd Once you have decided to solve a problem using Correct 6. P law problems using a simple example. Part F Newton's 2nd solution. One such prescription is the following Write equations for the constraints and other given information In this problem, the fact that the length of the string does not change imposes a constraint orn relative Visualize the problem and identify special cases. Isolate each body and draw the forces acting on it. Choose a coordinate system for each 8. accelerations of Find a acceleration of block 2, az. and the acceleration of block 1. Pay careful attention to signs . Express a block 1 in terms of ais and/or aiy, the components of the acceleration vector of 9 10. (Figure 1 Hints 1of 2 12. 13. block 2 Submit My Answers Give Up 14. Part G block I 15. This question will be shown after you complete previous questions) Proxide Eeedback

Explanation / Answer

Block 1 is hanging over a cliff falling down, and block 2 is on the cliff, being dragged by block 1, then

(a_2x) = -(a_1y)

[Any time one is pulling the other, using the tension of the string, then the constraint is that the magnitude of a1 is equal to the magnitude of a2.]
