How do you calculate resultant velocity?

How do you calculate resultant velocity?

Divide the total momentum by the sum of the masses if the two objects stick together after impact. This will give you the resultant velocity of the two objects. In the example above, we would take 50 and divide by the sum of the masses, which is 10, getting a result of 5 meters per second.

How do you find the resultant speed and direction of a plane?

the resultant velocity of the plane is the vector sum v = v1 + v2, where v1 is the velocity vector of the plane and v2 is the velocity vector of the wind. the angle between v1 and v2 is pi/4.

What is the resultant velocity of the plane?

The resultant velocity of the plane (that is, the result of the wind velocity contributing to the velocity due to the plane’s motor) is the vector sum of the velocity of the plane and the velocity of the wind. This resultant velocity is quite easily determined if the wind approaches the plane directly from behind.

What is the velocity vector of the plane’s tailwind?

For a tailwind, the wind velocity vector would be drawn in the same direction as the plane velocity. The resultant vector stretches from the tail of the first vector (plane velocity) to the head of the last vector (wind velocity).

How do you find the resultant velocity?

Quick Answer. Resultant velocity is the vector sum of all given individual velocities. Velocity is a vector because it has both speed and direction. There are many ways to calculate vector sums, such as using a vector addition diagram, but using trigonometry to calculate vector components is usually more efficient.

How do you find the relative velocity of a plane?

The relative velocity of the plane with respect to the ground can be given as The angle between the velocity of the wind and that of the plane is 90°. Using the Pythagorean theorem, the resultant velocity can be calculated as, R 2 = (100 km/hr) 2 + (25 km/hr) 2

What is the angle between the velocity of the wind and plane?

Example: A plane is travelling at velocity 100 km/hr, in the southward direction. It encounters wind travelling in the west direction at a rate of 25 km/hr. Calculate the resultant velocity of the plane. The angle between the velocity of the wind and that of the plane is 90°.

How do you find the direction of a velocity vector?

The direction is calculated by finding the angle (theta) between the resultant velocity and the horizontal axis, (theta) = arctan(y/x), where x is the magnitude of the x component and y is the magnitude of the y component.
