Answer: The average velocity is -0.965m/s
Explanation: The first step is to calculate the two velocities is both directions. A velocity is a distance per unit time.
V=d/ t
=-5.7/2.1
=-2.7m/s
For the other direction the velocity is
V=7.3/9.5
=0.77m/s
The average velocity the add the velocities and divide them by 2.
V=-2.7+0.77/2
V= 0.965m/s
Answer:
The average velocity of the particle is 1.76 m/s.
Explanation:
Given that,
Distance = -5.7 m
Time t = 2.1 s
Forward distance = 7.3 m
Total time = 9.5 sec
We need to calculate the average velocity of the particle
Average velocity :
Average velocity is equal to the displacement divided by change in time.

Where, D = displacement
t = change in time


Hence, The average velocity of the particle is 1.76 m/s.
