There are two types of collision in physics which are named as elastic collision and inelastic collision.
Elastic collision is that type of collision in which both kinetic energy and momentum is conserved i.e total kinetic energy and momentum before collision is equal to the total kinetic energy and momentum after collision.As kinetic energy is conserved here,so less or ideally no damage occurs to the colliding bodies.
Inelastic collision is that type of collision in which only momentum is conserved but not kinetic energy .After the collision the kinetic energy is lost in forms heat,sound ,light etc.
Normally any deformation and destruction is due to the inelastic collision which results in the loss of kinetic energy.
Hence the helicopters were destroyed and deformed due to inelastic collision.
Answer:
- Binary
- Open cluster
- Globular cluster
Explanation:
A star system is a group of stars that orbit one another, through he influence of gravitational force. The Earth's star system is called solar system.
If you use the equation F=ma and re-arrange it to get m = F/a, you'll get the total mass. Then you have to subtract the mass of the cart from the total mass to get the mass of the rock.
Thus, m = 6N over 2m/s^2. The total mass will then be 3kg. Subtracting 1kg from the total mass will then yield you 2kg, which is the mass of the rock. Hope this helps.

<em>✔ We have : a = v/Δt </em>
The car's acceleration is therefore 6 m/s².
A type of anchor that is a good choice when jacking or leveling the fastening component is a stud bolt anchor.
<h3>What is a Stud bolt anchor?</h3>
These are the type of anchor which bare embedded in concrete with the threaded portion on the outside.
This makes it easier to jack or level the fastening component which is why option B was chosen.
