According to the work-energy theorem, in the absence of friction, if you do 100J of work on a cart while pushing it across a horizontal surface, how much will you increase its kinetic energy?

Respuesta :

Answer:

100 J

Explanation:

Work energy theorem states that the work done between two points is equal to the change in kinetic energy between those two points.

So, doing a work of 100 J on a cart, with no friction present, increases the kinetic energy by the equivalent 100 J

Mathematically,

W = Δ K.E

100 J = Δ K.E

Δ K.E = 100 J
