According to the work-energy theorem, the amount of work done can be determined using which formula?

Respuesta :

W = KE = 1/2m(v2f-v2i) also known as D just took the test

Answer:

[tex]W=K_f -K_i = \frac{1}{2}mv_f^2 -\frac{1}{2}mv_i^2[/tex]

Explanation:

The work-energy theorem states that the amount of work done is equal to the variation of kinetic energy of the object, therefore:

[tex]W=K_f -K_i = \frac{1}{2}mv_f^2 -\frac{1}{2}mv_i^2[/tex]

Where:

m is the mass of the object

[tex]v_i[/tex] is the initial velocity of the object

[tex]v_f[/tex] is the final velocity of the object
