(a)
To find: The slope of the secants
(a)
Answer to Problem 7E
The units for the slope are
Secant | Slope |
Explanation of Solution
Given information: The below figure shows the distance-time graph for a
Calculation:
As shown in the graph the points are
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
The slope of the secant
So, the slope of the secant
Therefore, the units for the slope are
Secant | Slope |
(b)
To find: The speed at the point
(b)
Answer to Problem 7E
The speed at the point
Explanation of Solution
Given information: The below figure shows the distance-time graph for a
Calculation:
As calculated in part (a), the slope of the line joining the point nearest to the point
Therefore, the speed at the point
