Question

A particle moving along the circumference of a circle of radius 1m
completes 3/4 of a circle in 10 seconds.
what is the average velocity of the particle?​

Answer 1

Answer:

Radius of circle = 1m

completes 3/4 of circle = 270'

time = 10 sec

velocity of particle (w)= 270'x1/10

= 27m/sec

Answer 2

Answer:

0.1414

Explanation:

body covers 3/4 of a circle whose radius is 1m

distance travelled = 3/4 * 2 πr

but here average velocity= displacement/time

displacement =  √$1^{2} +1^{2}$  (by pythagoras theorem)

displacement=√2

avg V = 1.414/10 = 0.1414 m/s
