First, find the magnitude of v⃗ , that is, the speed v of the two-car unit after the collision.

1 answer:

3 0

The magnitude of v⃗ is {sqrt(m1v1)2+(m2v2)2/ m1+m2}, that is, the speed v of the two-car unit after the collision.

<h3>What is collision?</h3>

In physics, collisions occur when particles, aggregates of particles, or solids come close to each other, interact and affect each other.
Collisions are of three types Fully elastic collision, inelastic collision and Perfectly inelastic collision.
Multiply the mass of the second object by its velocity.
For example, if the weight is 1,000 and the speed is -30 meters per second, then its momentum is 30,000 kg meters per second.
Add the two velocities together to determine the direction the object will move after a collision.
So the formula for determining the size of a vector (in 2D space) is v = (x, y).|v| = √(x2 + y2).
This formula is derived from the Pythagorean theorem.
The formula V = (x, y, z) that determines the size of a vector (in 3-dimensional space) is:|V| = √(x2 + y2 + z2)
