To find velocity, we need to calculate the total displacement and divide by the total time taken. April's total displacement is 30 meters north (50 m - 20 m south). Velocity is calculated as displacement/time, so her velocity is 0.5 m/s (30 m / 60 s).
The displacement of the car is 200 m (250 m north - 50 m south). The time taken is 15 seconds. Therefore, the velocity of the car is 200 m divided by 15 seconds, which equals 13.33 m/s north.
Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).
The car's net displacement is 0 miles (north 50 miles - south 50 miles). Since the total time taken is 5 hours, the velocity is 0 mph because velocity is displacement divided by time, resulting in 0 mph.
You said "against ... wind", and that's all the information I have that specifies the direction of the wind. I have to understand that to mean that the wind is from the south toward the north. In that case, the wind vector is exactly opposite to the duck vector. So, during the gust, the duck's ground speed is (10.0 - 2.5) = 7.5 ms.
Velocity is speed and its direction. "30 miles per hour" is a speed. "30 miles per hour north" is a velocity". "30 miles per hour north" and "30 miles per hour south" are identical speeds but different velocities.
If April swam 50 M North then swam 20 M South back then her velocity would be 16.66. This is a math problem.
.5 north
Displacement: 8 m south Time: 4 seconds Therefore velocity = 2 metres per second Southwards.
He walked 600m in 600 seconds so his velocity is 1m/s (one metre per second)
The displacement of the car is 200 m (250 m north - 50 m south). The time taken is 15 seconds. Therefore, the velocity of the car is 200 m divided by 15 seconds, which equals 13.33 m/s north.
1.5 m.s north thanks to m.e.h :D
Velocity is distance/time. So, 2000/400 reduces to 5 m/s, but since velocity is a vector, direction MUST be stated along with the speed we just calculated. The final answer is 5 m/s South (or 270 degrees).
20 m/s north
The person travels a total of 4000 m in 400 seconds, so their average speed is 10m/s. However velocity is a vector quantity, and is defined as displacement/time. The total displacement is only 400 m, so the average velocity is just 1m/s.
5 m/s south
No. Velocity is described as a speed in a certain direction. Since they are in different directions, they are different velocities.
What I mean is can you have a negative velocity followed by "south". (i.e. -7.5 m/s south) or would the velocity be 7.5 m/s south? My opinion is that the negative sign is not necessary since south is already "negative" so you would be canceling out the negative if you have the sign making it 7.5 m/s north.
