Question

What was the acceleration during the segment labeled "A"?

Answer 1

Answer:

$a = 4 m/s/s$

Explanation:

As we know that the acceleration of an object is defined as the rate of change in velocity of the object

so we can say it is given as

$a = \frac{dv}{dt}$

so if we have a graph of velocity and time then rate of change in velocity is given by the slope of v-t graph

so here for segment A slope of the graph is

$a = \frac{v_2 - v_1}{\Delta t}$

$a = \frac{20 - 0}{5 - 0}$

$a = 4 m/s/s$

Answer 2

5 m/s/s because you solve it using the formula......change in velocity ÷ Elapsed Time
