Final kinetic energy will be equal to (Initial kinetic energy) plus (work that you do to turn it around).
KE = 1/2 m V2
Initial KE = 1/2 (0.026) (13)2 with 'V' pointing left.
Final KE = 1/2 (0.026) (49)2 with 'V' pointing right.
You have to supply the difference = 1/2 (0.026) (62)2 = 49.972 kg-m2/s2 = 49.972 newton-m
= 49.972 joules

When a particle is moving in a circular motion at a constant speed, the work done by the particle is zero. This is because work is defined as force applied over a distance in the direction of the force, and in circular motion, the force and displacement are perpendicular to each other, resulting in no work being done.
The formula for the work done by an electric field on a charged particle is given by W qEd, where W represents the work done, q is the charge of the particle, E is the electric field strength, and d is the distance the particle moves in the field.
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
In the scientific definition of work, magnetic and electric fields can do work on charged particles that are moving through them. The work done is based on the force exerted by the field on the particle and the distance over which the particle is displaced.
The work done by an electric field on a charged particle as it moves through a given distance is equal to the product of the electric field strength, the charge of the particle, and the distance it moves in the direction of the field. This work done is measured in joules.

done do did done
If you do not have a problem moving you face or nose when the septum is done right.
cause you cant get the job done right

The past participle of do is 'done'.

It is done by moving the decimal point 7 places to the right, to give: 94000000
The work done by an electric field on a charged particle as it moves through a given distance is equal to the product of the electric field strength, the charge of the particle, and the distance it moves in the direction of the field. This work done is measured in joules.
When a charged particle is moved along an electric field line, it will experience a force in the direction of the field line. The work done on the particle depends on the distance it moves and the strength of the field. If the particle moves perpendicular to the field lines, then no work is done by the field.
