25. Velocity-time graph of a particle moving along x axis is shown in figure.
at t = 0.x coordinate of the particle is x = 10m
a. Plot displacement time graph.
b. Find average velocity and average speed of particle during complete journey
Find the average acceleration of the particle between the time integral from
2sec tot =8sec
C
Answers
Explanation:
the total displacement 0s to 6s is D and the time is t.
The average velocity from 0s to 6s is given as,
v
avg
=
t
D
=
6
10+0+10−20
=0m/s
Since, the instantaneous velocity at a time is equal to the slope of velocity time graph at that time.
The instantaneous velocity at 3s is given as,
v
i
=0
Thus, the average velocity from 0s to 6s is 0m/s and the instantaneous velocity at 3s is 0m/s.
