Answer:
Following are the option are the correct option to the given question
- Plane landing on an aircraft carrier.
-
Rain sticking to a window.
-
Two train cars coupling together.
Explanation:
In the inelastic collisions is the kinetic energy is not preserved because of the some internal friction.In the elastic collision there is shortage of the kinetic capacity.
- When the airplane is landing it has always been in contact with the surface to relieve the inelastic collision condition.
- When then rain falls the clinging to the door once it intersect with as well so it is satisfied the condition of inelastic collision.
- When the two train or cars collide there is loss of kinetic energy so it is satisfied the condition of inelastic collision.
- All the other option is not the example of inelastic collision that's why they are incorrect option.

Answer:
For ball P=- 2 x m x V.
For P= - m x V
Explanation:
As we know that
if external force is zero then linear momentum of system will be conserve.
Rubber ball:
Given that speed of ball is V before the collision with ball.
The speed of the ball is remain after the collision with ball but the direction will reverse.
Lets take first ball is moving in positive x direction and after collision with ball it moves in negative x direction.
Initial momentum
Finall momentum
So the change in the momentum
P=- 2 x m x V.
For clay:
Initial velocity of clay is V in positive x direction and final velocity is zero because it stick with the wall
So the change in the momentum
P= - m x V.
Two of Newton's laws, properly combined with geometry and calculus, then mixed, stirred and massaged, produce orbital motion.
==> Law of universal gravitation (gravity)
==> Second law of motion ( F=ma ).
Answer:
181 m
Explanation:
a = v² / r
6.09 (9.81 m/s²) = (104 m/s)² / r
r = 181 m
