The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)
The velocity of the object is 10 m/s.
The minimum velocity of the missile would depend on the time it takes for the missile to reach the target. If the missile travels 100 meters in 1 second, then the minimum velocity would be 100 m/s.
500 meters/5 minutes = 100 meters per minute.
Yes. Velocity is a vector and therefore requires magnitude and direction: Magnitude: 100 kph Direction: North
The resultant velocity of a plane is 75 km/hr.
The resultant velocity of a plane is 125 km/hr.
Velocity = Distance ÷ Time, therefore : Time = Distance ÷ Velocity. Time for journey = 877 ÷ 100 = 8.77 hours = 8 hours 46 minutes 12 seconds.
The closing velocity is speed1 plus speed2, so the trains are moving toward each other at 250 mph. 2000/250 = 8. The trains will meet in 8 hours.
Yes, the International Space Station ISS travels round the world in just 92.89 minutes.
Think of average velocity as "overall" velocity. For example, if I walk down the block (let's say it's a distance of 100 meters), and it takes me 5 minutes, my AVERAGE velocity is just:v_ave = Δx/Δtwhere Δx is the change in position and Δt is the elapsed time.v_ave = (100 m) / (5 min)v_ave = (100 m) / (300 sec)v_ave = (1/3) m/sBut instantaneous velocity is a different concept: let's say for a while I walked, then I jogged, then I stopped, then I sprinted, then I walked. The overall trip still ended up taking me 5 minutes, so my average velocity is just as I've calculated it above, but my INSTANTANEOUS velocity changes as I change speeds at any given time in between.Hope this helps!
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
250 metres in 2.5 minutes = 250/2.5 = 100 metres per minute.250 metres in 2.5 minutes = 250/2.5 = 100 metres per minute.250 metres in 2.5 minutes = 250/2.5 = 100 metres per minute.250 metres in 2.5 minutes = 250/2.5 = 100 metres per minute.
