Question

A particle is moving
with a constant
speed v in a circle.
What is the
magnitude of
average velocity
after half rotation?​

Answer 1

Answer:

A particle starts from points A with constant speed V on a circle of radius R find magnitude of average velocity after half revolution Please solve this question. Answer is 2v / π.

Explanation:

Please make me the brillients

Answer 2

Answer:

Diameter =2× radius =2R

Distance covered = Half of circumference

=πR

⇒ Speed =

Time

Distance

Time =

speed

Distance

=

V

πR

Average Velocity =

Totaltime

TotalDisplacement

=

πR

2R×v

=

π

2v

Hence, the answer is

π

2v
