An elevator is moving up with an acceleration of 3.36 m/s^2. What would be the apparent weight of a 64.2 kg man in the elevator?

A)215.71 N
B)413.45 N
C)844.87
D)Need more information

ok I got 847.44 but as you can see that's not an answer choice so my guess is D, need more information.

    The answer is M(a + g) = 64.2(9.806 + 3.36) = 845.3 N
    The closest answer is C. You will get their exact "C" answer if you use 9.8 m/s^2 for g.
