Question

А.
1.0 m
4. 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
(a) 3.14 m/s
(b)(2.0 m/s
(c) 1.0 m/s
(d) Zero
B'​

Answer 1

Answer:

(b)

Explanation:

since displacement is 2r i.e 2*1.0m=2m

therefore velocity = 2/1 m/s = 2m/s
