The entangled velocity of the cars after the collision is 2.7 m/s.
<h3>What is velocity?</h3>
Velocity is the rate of change of displacement. The S.I unit of velocity is m/s.
To calculate the velocity of the entangled cars after the collision, we use the formula below.
Formula:
- mu+MU = V(m+M).............. Equation 1
Where:
- m = mass of the car
- M = mass of the truck
- u = initial velocity of the car
- U = initial velocity of the truck.
- V = velocity of the entangled car after the collision.
Make V the subject of the equation.
- V = (mu+MU)/(m+M)............ Equation 2
From the question,
Given:
- m = 2000 kg
- M = 18000 kg
- u = 0 m/s (at rest)
- U = 3 m/s
Substitute these values into equation 2
- V = [(2000×0)+(18000×3)]/(2000+18000)
- V = 54000/20000
- V = 2.7 m/s.
Hence, the entangled velocity of the cars after the collision is 2.7 m/s

Answer:
According to our present theory of solar system formation, why were solid planetesimals able to grow larger in the outer solar system than in the inner solar system? Because only metal and rock could condense in the inner solar system, while ice also condensed in the outer solar system.
Explanation:
Answer:
It becomes wider
Explanation:
Because The bigger the object the wave interacts with, the more spread there is in the interference pattern. Decreasing the size of the opening increases the spread in the pattern.
Answer:
Height of the cube under water will be 3.33 cm
Explanation:
We have given height of the cube = 5 cm
Density of the material
Density of liquid
We have to find the height of the cube under the water
Height under water is given by
Height under water =
Height of the cube under water will be 3.33 cm
