Problem

A displacement vector is d⃗=4 i^−3 j^  m\vec d = 4\,\hat i - 3\,\hat j\;\text{m}. Find the magnitude of d⃗\vec d and the angle θ\theta it makes with the positive xx-axis measured anticlockwise (0∘≤θ<360∘0^\circ \le \theta < 360^\circ). a) 5 m,  37∘5\,\text{m},\;37^\circ b) 5 m,  323∘5\,\text{m},\;323^\circ c) 5 m,  143∘5\,\text{m},\;143^\circ d) 7 m,  323∘7\,\text{m},\;323^\circ
