Abird flies from the south pole to the north pole. part of the journey is 1000 miles that takes 2 weeks. what is the bird’s velocity in that time? show work for credit and include final units.
Abird flies from the south pole to the north pole. part of the journey is 1000 miles that takes 2 weeks. what is the bird’s velocity in that time? show work for credit and include final units.
We Know, Velocity = Distance / Time
Here, Distance = 1000 miles
Time = 2 weeks = 14*24 Hours [ 1 week = 7 days & 1 day = 24 hours ]
Time = 336 Hours
Now, substitute the values,
Velocity = 1000/336 = 2.976 miles/hour
So, your final answer is 2.976 miles/hour
Hope this helps! Happy studying 🙂
Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called "speed", being a coherent derived unit whose quantity is measured in the SI (metric) system as metres per second (m/s) or as the SI base unit of (m⋅s−1).
1000 miles = 1610km = 1.61x10^6m
2 weeks = 14 days = 14x24x1440
V=d/t = 1.61x10^6/14x24x1440
= 3.33m/s
The correct answer to the question is : 2.976 miles/hour.
CALCULATION:
As per the question, the distance travelled by the bird X = 1000 miles.
The time taken by the bird to cover that distance t = 2 weeks.
= 2 × 7× 24 hours
= 336 hours
We are asked to calculate the speed of the bird.
The speed of the bird is calculated as -
speed v = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{1000}{336}\ miles/hour[/tex]
= 2.976 miles/hour [ans]
Hence, the velocity of the bird is 2.976 miles/hour.
Based from the basic formula and relationship of distance, time and velocity, it is said that velocity is equal to distance traveled over time covered. The bird has a velocity of 1000/2 or equivalent to 500 miles per week. This can also be expressed in some other units such as km/h. m/s etc.
Two weeks is
[tex]2 weeks \times \frac{7 days}{1 week}\times \frac{24 hours}{1day}=336hours[/tex]
Then the speed is
[tex]\frac{1000miles}{336hours}=2.97 \frac{miles}{hour}[/tex]
Velocity = Distance / TimeHere, Distance = 1000 milesTime = 2 weeks = 14*24 Hours [ 1 week = 7 days & 1 day = 24 hours ] Time = 336 Hours
Now, substitute the values,Velocity = 1000/336 = 2.976 miles/hour
So, your final answer is 2.976 miles/hour

2 weeks = 14 days = 336 hours
1000 miles / 336 hours = 2.976mph
