FORCE, MASS, AND ACCELERATION.
I don't understand this question...
A sky diver weighing 500N free falls through the air at a steady speed of 50m/s.
a) draw a diagram of the forces acting on her.
(how do we draw a diagram of this? )
b) what is the air resistance acting on her, in Newtons? Explain your answer.
c) what is her mass?
If there is constant velocity, there must be no net force. But the diver weighs 500N, so air resistance must be...
