Each of the three barges has a mass of 30 Mg, whereas the tugboat has a mass of 12 Mg. As the barges are being pulled forward with a constant velocity of 4 mis, the tugboat must overcome the frictional resistance of the water, which is 2 kN for each barge and 1 .5 kN for the tugboat.
You can use the principle of conservation of momentum to measure characteristics of motion such as velocity. After the hit, the players tangle up and move with the same final velocity. Therefore, the final momentum, pf, must equal the combined mass of the two players multiplied by their final velocity...

The velocity of money can be calculated as the ratio of nominal gross domestic product (GDP) to the money supply (V=PQ/M), which can be used to gauge the economy’s strength or people’s willingness to spend money. When there are more transactions being made throughout the economy, velocity increases, and the economy is likely to expand.

The velocity distribution for fluid flow over a flat plate is given by u=2y-6y 2 in which u is the velocity in metre per second at a distance of y metre above the plate. Determine the shear stress at y=0.15m.Take dynamic viscosity of fluid as 8.6 poise.
The negative sign for acceleration indicates that acceleration is toward the west. An acceleration of 8.33 m/s 2 due west means that the horse increases its velocity by 8.33 m/s due west each second, that is, 8.33 meters per second per second, which we write as 8.33 m/s 2. This is truly an average acceleration, because the ride is not smooth.
Instantaneous Velocity. The quantity that tells us how fast an object is moving anywhere along its path is the instantaneous velocity, usually called simply velocity.It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero.
