To solve this problem we will apply the concepts related to the work theorem for which it is defined as the product of Force and distance. In turn, we will use the energy conservation theorem for which the applied work must be equivalent to the total kinetic energy on the body.
The work is defined as
Here,
F = Force
d = Displacement
Replacing with our values we have that
Now by conservation of energy,
Solving for v,
Therefore the correct answer is D.
Answer:
The value is
