Question

In one second a particle goes from point a to point b in a straight line. What is the magnitude of avg velocity

Answer 1

Although the particle moves around semicircle, the displacement is diameter of the semicircle and hence total displavement upon total time is average velocity here

Answer 2

Answer:

heya..

If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length

i hope its help u
