Average velocity while walking

In summary, to compute average velocity in the two given cases, you need to find the total distance traveled and the corresponding times for each leg of the journey. For the first case, the total distance is 59.5 m and the total time is the sum of the time it takes to walk 59.5 m at 2.16 m/s and the time it takes to run 59.5 m at 4.01 m/s. For the second case, the total distance is also 59.5 m, but the total time is the sum of the time it takes to walk for 1.00 min at 2.16 m/s and the time it takes to run for 1.91 min at

Homework Statement



Compute your average velocity in the following two cases: (a) You walk 59.5 m at a speed of 2.16 m/s and then run 59.5 m at a speed of 4.01 m/s along a straight track. (b) You walk for 1.00 min at a speed of 2.16 m/s and then run for 1.91 min at 4.01 m/s along a straight track.

Homework Equations



i have vavg = delta x/ delta t

but there is no time.. in the first part of the problem..

The Attempt at a Solution



i'm too confused :(

Average speed = total distance/total time

total time = time of first leg of journey + time of second leg of journey

time of first leg of journey = distance of first leg/speed of first leg

time of second leg = distance of second leg/speed of second leg

Got it?

Yes there is no time given. Can you find the appropriate times? How many seconds does it take you to travel 59.5 m if for every second that goes by you move 2.16 meters? Same approach for the second leg of the trip in question (a).

i definitely do get it now, thank you!

if only my teacher would actually teach :)
 

Related to Average velocity while walking

What is average velocity while walking?

The average velocity while walking is the average speed at which a person moves while walking. It is measured in units of distance over time, such as miles per hour or meters per second.

How is average velocity while walking calculated?

The average velocity while walking is calculated by dividing the total distance traveled by the total time taken to travel that distance. This can be expressed as the ratio of displacement over time, or by taking the average of the instantaneous velocities at different points during the walk.

What factors can affect average velocity while walking?

Several factors can affect average velocity while walking, including the terrain or surface being walked on, the person's physical fitness level, and any external forces acting on the person (such as wind or gravity). Additionally, factors such as age, height, and weight may also impact a person's walking speed.

How does average velocity while walking differ from average speed?

Average velocity while walking and average speed are often used interchangeably, but they are not exactly the same. While average velocity takes into account the displacement of an object, average speed only considers the total distance traveled. This means that average velocity is a vector quantity, while average speed is a scalar quantity.

Why is average velocity while walking important to study?

Studying average velocity while walking can provide valuable insights into a person's physical abilities and overall health. It can also help in analyzing and improving walking techniques, as well as understanding the mechanics of human movement.
