Question

Questions : 1. What is the penguin’s average velocity during the chase? 2. What is the penguin’s average speed during the chase?

Answer 1

Given:

• Distance traveled rightward = 6 m

,

• Distance traveled leftward = 10 m

,

• Total time, t = 30 s

Let's solve for the following:

• (1). What is the penguin’s average velocity during the chase?

To find the average velocity, apply the formula:

`v=(d)/(t)`

Where:

• v is the average velocity in m/s

,

• d is the displacement

,

• t is the total time in seconds.

The displacement given a 6 meters rightward move and 10 m leftward move is:

d = 6m + (-10 m) = 6m - 10m = -4 m

Thus, we have:

`\begin{gathered} v=(-4)/(30) \\ \\ v=-0.13\text{m/s} \end{gathered}`

The average velocity is -0.13 m/s.

• (2). What is the penguin’s average speed during the chase?

To find the average speed, we have:

`v=(d)/(t)`

v is the average speed in m/s

d is the total distance = 6m + 10m = 16m

t is the total time = 30 s

Thus, we have:

`\begin{gathered} v=(16)/(30) \\ \\ v=0.53\text{ m/s} \end{gathered}`

The average speed is 0.53 m/s.

ANSWER:

0. Average velocity = -0.13 m/s

,

1. Average speed = 0.53 m/s
