Problem 26E

Hearing rattles from a snake, you make two rapid displacements of magnitude 1.8 m and 2.4 m. In sketches (roughly to scale), show how your two displacements might add up to give a resultant of magnitude (a) 4.2 in; (b) 0.6 m; (c) 3.0 m.

Step-by-Step Solution:
Step 1 of 3

Solution 26E Let us have a look at the possible three situations given in figures. Case 1: Both displacements can happen along the same direction, one after another as shown in the figure above. In this case, the resultant displacement = 1.8 m + 2.4 m Resultant displacement = 4.2 m Case 2: In this case, my first displacement can be 1.8 m in one direction and then 2.4 m in the opposite direction. The resultant displacement can be calculated as = 2.4 m 1.8 m = 0.6 m. The...
