The graph represents velocity over time.

a graph with horizontal axis time (seconds) and vertical axis velocity (meters per second). a line runs from 0 seconds 2 meters to 100 seconds 22 meters.

what is the acceleration?

–0.4 m/s2
–0.2 m/s2
0.2 m/s2
0.4 m/s2

0.2ms^{-2}

Explanation:

acceleration can be taken as the gradient of a velocity - time graph

let the points be (0,2) (100,22)

Explanation:

As we know that rate of change in velocity is given as acceleration

Here we know that

here we know that

now we have

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
