Question

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

Answer 1

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

Answer 2

`a = 4 m/s/s`

Step-by-step 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 = (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 = (v_2 - v_1)/(\Delta t)`

`a = (20 - 0)/(5 - 0)`

`a = 4 m/s/s`
