Question

A velocity vs. time graph is shown.

Answer 1

Answer:

Acceleration, $a=4\ m/s^2$

Explanation:

We are given with a velocity-time graph of an object that starts from origin. y axis is velocity and x-axis is time.

The slope of velocity-time graph gives acceleration of an object. Taking the slope of this graph.

$m=\dfrac{v}{t}\\\\m=\dfrac{20\ m/s}{5 s}\\\\m=\text{acceleration}=4\ m/s^2$

So, the acceleration of the object is $4\ m/s^2$.
