A weighs 600 N on an elevator when it is stationary. Each elevator accelerates according to the specified arrow that is drawn next to it. In all cases where the elevator is moving, it is moving downward.

Find net force, if the elevator is accelerating 2.0 m/s/s upward, even though the elevator is moving downward. Use g = 9.8 m/s/s

2. Relevant equations

w = mg

F = ma

3. The attempt at a solution

Well this is what i did: F = ma

Fn - mg = ma

Fn = ma + mg

Fn = 61.2(2) + 61.2(9.8)

Fn = 722.4 N

Is that right?
