MCQ
In $1.0\, s$ a particle goes from point $A$ to point $B$, moving in a semicircle of radius $1.0\, m$ (see figure). The magnitude of the average velocity is ......... $m/s$
- A$3.14$
- ✓$2.0$
- C$1.0$
- D$0$
✓
Answer
Correct option: B.
$2.0$
b
(b) Average velocity $ = \frac{{{\rm{Total \,displacement}}}}{{{\rm{time}}}} = \frac{{2\,m}}{{1\,s}} = 2\,m{s^{ - 1}}$
(b) Average velocity $ = \frac{{{\rm{Total \,displacement}}}}{{{\rm{time}}}} = \frac{{2\,m}}{{1\,s}} = 2\,m{s^{ - 1}}$
