Kyle's true weight is 600 N (magnitude), and her apparent weight at a certain time is 500 N
(magnitude). What is her acceleration at this time? Use g = 10.0 m/s. (Hint: What is her mass and
what is the net force?)
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
