Question 1 of 5 A cheetah runs with a positive acceleration . What does this tell you about the velocity-time graph for the cheetah? A. The graph has a positive area. B. The graph has a negative area. C. The graph has a negative slope. D. The graph has a positive slope.

## Step 1<br />The problem involves understanding the relationship between acceleration and the slope of a velocity-time graph. Acceleration is defined as the rate of change of velocity with respect to time. <br /><br />## Step 2<br />When an object has a positive acceleration, it means that its velocity is increasing over time. This is represented on a velocity-time graph by a line that slopes upwards. <br /><br />## Step 3<br />The slope of a line on a velocity-time graph represents the acceleration of the object. Therefore, a positive acceleration corresponds to a positive slope on the graph.
