Question

Which of the following graphs has a slope that indicates positive acceleration?

Answer 1

The last graph

Step-by-step explanation:

Acceleration is defined as the rate of change in velocity per unit time:

`a=(\Delta v)/(\Delta t)`

where
`\Delta v` is the change in velocity while
`\Delta t` is the change in time.

In a velocity-time graph, the acceleration also corresponds to the slope of the curve. Among all the graphs shown here, only the second one and the 4th one shows a velocity-time graph. Among these two, only the 4th graph shows a curve with positive slope: this means that the velocity is increasing, so the acceleration of the object is positive.

Answer 2

the last one.. cause that's the one where v(velocity) increases over time...
