Click For Summary
The backpacker walks 5.58 km west at an average velocity of 2.30 m/s before turning around and walking east at 0.430 m/s. To solve for the distance walked east, the average velocity formula (average velocity = displacement/elapsed time) is applied. The time taken to walk west is calculated as approximately 2426.09 seconds. The subsequent calculations for the eastward distance yield a value of approximately 1.043 km. The discussion highlights the importance of correctly applying the formulas for average velocity and displacement to find the solution.

Homework Statement



In reaching her destination, a backpacker walks with an average velocity of 1.09m/s, due west. This average velocity results, because she hikes for 5.58km with an average velocity of 2.30m/s due west, turns around, and hikes with an average velocity of .430 m/s due east. How far east did she walk ( in Km)

I have no idea on how to even go about this problem. I do know that average velocity = displacement/ elasped time... Like would i be solving it out three different times or plug it all in? Please let me knwo how to approach this problem Thank you!
 
Physics news on Phys.org
Find the time taken by her to hikes for 5.58km with an average velocity of 2.30m/s due west. Let d be the distance she hikes due east. Average velocity is given. Find the time to hike this distance in terms of d.
Now what is her net displacement?
What is the total time?
Net average velocity is given. Find d, and then the displacement.
 
So this is what i have following what you wrote, I'm not sure if I understood it all.

2.30m/s due west= 5580meter/t
t=.000412186

.430m/s=d/.00412186
d=.00017724

Did I do this correctly?? If so, I am not sure on what to do after this step.
 
v = d/t.
Then t = d/v
Check your maths.
 
I'm still getting it wrong...
.0023km/sec= 5.58/t
t=5.58/.0023
t=2426.0869sec

.00043=d/2426.0869sec
d=1.04321
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
