In 5 s, a particle goes from point A to point B moving in
a semicircle of radius 8 m as shown in the figure below.
The magnitude of average velocity of the particle is
A
8 m
B
2.3 m/s
3.2 m/s
5 m/s
1.3 m/s​

Answer 1

Answer:

Where is figure

Explanation:

any way avg. velocity is disp. upon time taken

disp 2r ---> 2×8 = 16 m

time taken 5s

divide both quantity u will get answer as 3.2 m/s
