You haven't specified the units you desire, KPH, MPH, or m/sec. Since m/s is a good "ending unit" without any conversion, then just do the math.
5m / 15s = (1/3)m/s = 0.33 m/s
This turns out to be just a little over 1 foot/second.
0.333333333 Recuring metres a second
If the person sat on the train their velocity relative to the ground would be 95kph. But he/she is goind 3kph to oppose this. So 95-3 = 92 kph to the north is velocity of person relative to the ground.
99.7 km/hr
Another car would have to travel at 70 km/hr west.To have the same velocity, it must have the same speed toward the same direction.
1.53 m/s towards the beach

at terminal velocity
A velocity vector would include both a speed and direction. Wind (air) resistance will affect the speed component, slowing down the arrow as time passes. Gravity will pull it downward at a constant acceleration of 9.8 m/s2. This means that the downward component of the velocity will increase with time. Wind, of course, could also throw the arrow off course.
It decreases.
A velocity vector.
at terminal velocity
terminal velocity
'Velocity' should be compared with 'speed', and it should be understood that they're different. "30 miles per hour" is a speed. "30 miles per hour toward the south" is a velocity.
50 / 2.5 = 20, same units as numerator of velocity
A dog running in a circle, stopping where it started, would have a net displacement of zero, an average velocity of zero, and an average acceleration of zero regardless of the time involved. This is because the dog has exerted equal work in moving toward his starting point as moving away from that point. A similar situation exists where a book is lifted from a desk and then dropped back : the book has the same potential energy as before it was lifted, the additional energy having been removed by the force of gravity.
In that case, the object is said to have achieved terminal speed.
As you may know that is one of the dancers. Do not be harmed of any kind of source. This person is just a dancer for the music video.
