Impulse is caused by a force during a specific time that is equal to the body's change of momentum
Impulsive force: the process of minimizing an impact force can be approched
A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Answer:
The change of the momentum of the ball is 
Explanation:
We should find 
(1)with 
the initial momentum and 
the final momentum. Linear momentum is defined as 
, using that on (1):
(2)
It's important to note that momentum and velocity are vectors and direction matters, so if +x direction is the direction towards the wall and the -x direction away the wall 
and 
so (2) becomes:

the mass number minus the atomic number
