I just did it

Answer 2

Answer: The velocity of the particle is -2 m/s

Step-by-step explanation:

Velocity is defined as the ratio of displacement of a particle to the time taken by the particle. The units of velocity is meters per second.

The equation representing velocity of a particle is given as:

`\text{Velocity}=\frac{\text{Displacement}}{\text{Time}}`

From the graph:

The particle has traveled a distance of 12 m in the downward direction in between 6 to 12 seconds.

Displacement of particle = -12 m

Time taken = 12 - 6 = 6 sec

Putting values in above equation, we get:

`\text{Velocity}=(-12m)/(6sec)=-2m/s`

Negative side represents the particle is moving in downward direction.

Hence, the velocity of the particle is -2 m/s
