Answer 1

Answer:

question is not understandable please re write the mistake

Explanation:

okkkkkkkkk that's alllllll

Answer 2

the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s. If the object is moving with an acceleration of -8 m/s/s, then the slope of the line will be -8 m/s/s. If the object has a velocity of 0 m/s, then the slope of the line will be 0 m/s. Because of its importance, a student of physics must have a good understanding of how to calculate the slope of a line. In this part of the lesson, the method for determining the slope of a line on a velocity-time graph will be discussed.

Let's begin by considering the velocity versus time graph above fig

The line is sloping upwards to the right. But mathematically, by how much does it slope upwards for every 1 second along the horizontal

slope=y2-y1/x2-x1 = ∆y/∆x
