Kinematics 1 Question 1
1. In $1.0 s$, a particle goes from point $A$ to point $B$, moving in a semicircle (see figure). The magnitude of the average velocity is
(1999, 2M)
(a) $3.14 m / s$
(b) $2.0 m / s$
(c) $1.0 m / s$
(d) zero
Show Answer
Answer:
Correct Answer: 1. (b)
Solution:
- $\mid$ Average velocity $\mid=\frac{\text { displacement }}{\text { time }}=\frac{A B}{\text { time }}=\frac{2}{1}=2 m / s$
