Question

if you move 60m from point 'A' to point 'B' and back to point 'A' in 20 seconds, then find
A. total distance
B. total displacement
C. average speed
D. average velocity

Answer 1

Answer:

displacement is zero

Explanation:

average speed =3m/s

average velocity =0

Answer 2

Answer:

distance is 120 m, and displacement is 0 , speed is 6 m/s and velocity is 0

Explanation:

1.it has moved 120 meters that's why its distance is 12o m

2.it has stated from the point and came back to that point that's why its displacement is 0 because displacement depends upon initial and final point

3.as displacement is 0 that's why velocity will be 0

4. speed = distance / time

=120/20

=6m/s

plz brain list me
