Question

A particle moves along a semicircle of radius 10 m in 5 seconds the average velocity of the particle is

Answer 1

Answer: 4 m/s

Average velocity = Total Displacement / Time taken

Displacement = 2 x Radius = 2 x 10m = 20m.

Time taken = 5s

⇒ Average velocity = 20/5 = 4 m/s.

Answer 2

Answer:

4 m/s

Explanation:

radius of circle=10 m

total displacement would be 2r=20m

total time is 5 sec

avg. velocity = 20 m/5 sec = 4 m/s
