Question

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

Answer 1

Acceleration is 0.2 m/s².

Answer 2

Acceleration is 0.2 m/s².

Step-by-step explanation:

From the graph below,

The x axis represents the time and the y axis represents the velocity.

Now, acceleration of an object is given as:

Acceleration,
`a=\frac{\textrm{Change in velocity}}{\textrm{Time interval for the change}}`

Now, from the below graph,

Change in velocity is,
`\Delta v=v_(final)-v_(initial)=22-2=20\textrm{ m/s}`

Time interval is,
`\Delta t=100-0=100\textrm{ s}`

Therefore,
`a=(\Delta v)/(\Delta t)=(20)/(100)=0.2\textrm{ }m/s^2`.

Acceleration is 0.2 m/s².
