QUESTION 28 You push a 80-kg file cabinet to the right on a frictionless horizontal surface with a force of 175 N from rest, the cabinet moves a distance of 12 m. What is the final speed of the cabinet, in m/s? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
