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
Velocity. Because 2 Km is(speed) and south direction
Just divide the distance by the time. The answer is in meters/second. If you want to convert that to the more commonly used kilometers/hour, multiply the number of meters/second by 3.6.
(79 km/hr) x (5.7 hr) = 450.3 kmThat's the displacement, if the direction of the velocity was constant throughout the trip.
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.
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.
That is incorrect. The distance travelled north cancels out the distance travelled south. Therefore - he only travels three blocks east.
no it is not, velocity includes speed and direction and while the speeds are the same the direction is not
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.
distance divided by time equals velocity... D/T=V Distance divided by time equals velocity.. D/T= V as in: Furlongs per fortnight V = d / t The average velocity of an object is given by the distance traveled divided by the time it took.
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.
