Solve the following problem given below:
Problem: A toy soldier attached to a parachute with a mass of 1.8 g is thrown from a second story balcony. A few seconds later the velocity of the parachute toy is measured-it is falling down at constant speed of 18 m/s.
A- What is the force of air drag on toy soldier's parachute?
