The figure shows a graph of electric potential versus position along the x-axis. A proton is originally at point A, moving along
in the positive x direction. How much kinetic energy does it need to have at point A in order to be able to reach point E (with no forces acting on the proton other than those due to the indicated potential)? Points B, C and D have to be passed on the way.

In order to solve the problem, it is necessary to apply the concepts related to the conservation of momentum, especially when there is an impact or the throwing of an object.
The equation that defines the linear moment is given by
where,
m=Total mass
Mass of Object
Velocity before throwing
Final Velocity
Velocity of Object
Our values are:
Solving to find the final speed, after throwing the object we have
We have three objects. For each object a launch is made so the final mass (denominator) will begin to be subtracted successively. In addition, during each new launch the initial speed will be given for each object thrown again.
That way during each section the equations should be modified depending on the previous one, let's start:
A)
B)
C)
Therefore the final velocity of astronaut is 3.63m/s
