Answer 1

Explanation:

hope you understand the solution

Answer 2

Answer:

distance =3/2pi*r

Displacement=$\sqrt{2} r$

Explanation:

we have to find

magnitude of the displacement of the object.

Displacement =AD

=$\sqrt{r^{2} +r^{2} } \\\sqrt{2} r$

Distance covered by the moving object

Distance=

$\frac{3}{4} (2\pi r)\\\\=\frac{3}{2} \pi r$
