A man descends on a parachute moving uniformly by the force of gravity of the parachutist together with a parachute of 700 Newtons. What is the force of air resistance.
Ft = 700 N.
Fsopr -?
According to 1 Newton’s law: a body is in a state of uniform rectilinear motion if no forces act on it or the action of all forces is compensated.
Since the skydiver moves evenly, the force of gravity is compensated by the force of air resistance.
Ft = Fcomp.
Fcopr = 700 N.
Answer: the force of air resistance is Fcopr = 700 N.
