First, the acceleration is measured m / s 2
F = am
a normal g = 9.8 m / s ^ 2
F air resistance = gm – am
F = m (g-a) = 3 * (9.8-8)
F = 3 * 1.8 = 5.4 N
Answer 5.4.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
