A moving electron has a Kinetic Energy K1. After a net amount of work is done on it, the electron is moving one-quarter as fast in the
opposite direction. What is the work done W in terms of K1?
Solution
To solve for the work done, first we must determine what is the final kinetic energy of the electron.
By concept, we know that
K1=(1/2)mv2,
K2=(1/2)mv2
But it was mentioned that:
V2=(
V1
so, K2 in terms of v1 is
K2=(
)mv2,
Substituting the expression for K, results to
K2=(
K1
Since work done is
W=AK=K
Evaluating results to
W=(
)K1
