Chapter 2.3, Problem 25SSC

To determine

The time taken by the puck to go from $40\text{m}$ beyond the origin to $80\text{m}$ beyond the origin.

Answer to Problem 25SSC

  $2.0\text{s}$

Explanation of Solution

Given:

The position versus time graph.

The time taken by the hockey puck to travel a distance of $40\text{m}$ from the origin is, $t_1=2.0\text{s}$ .

Similarly, the time taken by the hockey puck to travel a distance of $80\text{m}$ from the origin is, $t_2=4.0\text{s}$ .

Calculation:

Consider the given position versus time graph.

Then, the time taken by the hockey puck to travel from the distance of $40\text{m}$ to $80\text{m}$ is:

  $\begin{array}{c}t=t_2-t_1\\ =\left(4.0-2.0\right)\text{s}\\ \text{=}\text{2}\text{.0}\text{s}\end{array}$

Conclusion:

Thus, the time taken to go from $40\text{m}$ beyond the origin to $80\text{m}$ beyond the origin is $\text{2}\text{.0}\text{s}$ .
