20 m/s north
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.
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).
Velocity has a speed and direction i.e. + 55 mph could mean North and -55 mph would mean South Speed is just the magnitude i.e. 55mph. Averaging the speed could be zero if you went 55mph North and 55 mph South.
Velocity is speed and direction. The velocity would be zero because the 50 miles N cancel the 50 miles S. The speed is 100 mi/5 h = 20 mph.
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)
1.5 m.s north thanks to m.e.h :D
During April, the sun is moving from south to north, heading north.
20 m/s north
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.
