Question

What is the acceleration of this object? The object's mass is 60 kg. Box with dot in center. Short arrow up, longer arrow down. Up arrow labeled F sub air equals 400 N. Down arrow labeled F sub grav equals 600N. 0 m/s2 3.3 m/s2 6.7 m/s2 10 m/s2

Answer 1

$\sum \overrightarrow F = m \overrightarrow a \\ \\ \sum F_y = 600N - 400N = 200N \\ \\ \sum F_y = m a_y \\ \\ a_y = \frac{\sum F_y}{m} = \frac{-200N}{60 kg} = 3,33 \frac{m}{s^2}$
