Consider two displacements, one of magnitude 12 m and another of magnitude 16 m. What angle between the directions of this two displacements give a resultant displacement of magnitude (a) 28 m, (b) 4 m, and (c) 20 m.
Added by Jason C.
Step 1
We want to find the angle $\theta$ between the two displacements such that the magnitude of the resultant displacement $R$ is equal to the given values. We can use the law of cosines to find the magnitude of the resultant displacement: $R^2 = A^2 + B^2 - Show more…
