)In 1.0 s, a particle goes from point A to point B,moving in a semicircle of radius 1.0 m. Themagnitude of the average velocity is

Answer»

Displacement = Shortest Distance between initial and final position.

When it travels a semicircular path then it’s displacement is equal to diameter of circle i.e 2r

Therefore displacement = 2 x 1 m = 2 m

Average velocity = Displacement / Time= 2 /1 = 2 m/s

Average velocity of particle is 2 m/s
