a high speed train travels south for 2.00 h for a distance of 454km. what is its average velocity?
Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour. Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2 = -5 miles per hour or, velocity due South = 5 miles per hour.
The resultant velocity of a plane is 75 km/hr.
14 miles
To find the time it takes for the soccer ball to travel 6.5 meters at a velocity of 22 meters per second, you can use the formula: time = distance/velocity. Plugging in the values, time = 6.5 meters / 22 meters per second, which equals approximately 0.295 seconds. Therefore, it would take the ball about 0.3 seconds to travel that distance.
Velocity. Because 2 Km is(speed) and south direction
(79 km/hr) x (5.7 hr) = 450.3 kmThat's the displacement, if the direction of the velocity was constant throughout the trip.
Joe has ridden a distance of 3.125 km in 15 minutes since velocity is distance traveled divided by time taken.
That is incorrect. The distance travelled north cancels out the distance travelled south. Therefore - he only travels three blocks east.
Average speed = Total Distance/Total Time = (15+25)/2 = 40/2 = 20 miles per hour. Velocity (due North) = Total NET distance North/Total Time = (15-25)/2 = -10/2 = -5 miles per hour or, velocity due South = 5 miles per hour.
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.
Velocity is how fast and what direction. The formula for this is distance over time, indicating the direction. (North East, South or West.) Speed is how fast something is moving. Speed is like velocity except velocity indicates direction. The formula is distance divided by time. Hope that helps. :)
Simply divide the distance traveled by the time.
The resultant velocity of a plane is 75 km/hr.
They are incompatible and can't be converted from one another. In order to get a velocity you would also need the time spent to cover the distance. Then you can use the formula distance/time=velocity. For example if you travelled 120 miles in 3 hours, you've travelled at 40 mph. If you have covered 200 kilometers in 4 hours, you've travelled 50 kilometers per hour.
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.
Speed is the distance travelled in a given period of time and is measured in metres per second or miles per hour (ie 'distance' per 'unit of time'). It is always a positive number. Velocity, however,, is the sppeed of an object in a given direction. So that if you define ''forwards' as a positive velocity, then if the object travels 'backwards', that would be classed as a negative velocity. So, if a car travels forwards, say, at 30 mph, its speed will be 30mph and its velocity will also be 30mph. However, if the car returns at the same speed, its speed will still be 30mph but its velocity will be - 30mph (minus 30mph) as the car is travelling in the opposite direction. This may seem a pointless exercise, but in equations of motion that involve speed, velocity, accceleration, time and so on, the direction of travel is important and so the velocity is used rather than speed. The concept of velocity is used in space travel, satellite technology, calculating flight paths, calculating missile trajectories and so on and so direection of travel - and hence velocity - is of vital importance.
