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)

1) the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Answer:
30 m/s
Explanation:
Vf = ?
Vi = 0 m/s
a = 20 m/s^2
t = 1.5 s
Plug those values into the equation: Vf = Vi + at
Vf = 0 + (20)(1.5)
Vf = 30 m/s
Answer:
<em>Physical change is a temporary change. A chemical change is a permanent change</em>
<em>examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.</em>
