Hearing rattles from a snake, you make two rapid
Chapter 1, Problem 26E(choose chapter or problem)
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.

QUESTION:
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.
ANSWER: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 di
