A movie features dangerous stunts including jumping from a helicopter, riding on the hood of a speeding car, and a number of other acrobatic stunts. The director has hired a stunt double to perform these stunts. In the filming of the helicopter scene, the stunt double is released from a height of 10,000m. Assume the only forces acting on the stunt double are gravity and air resistance. The force of air resistance is assumed to be proportional to the velocity with proportionality constant λ = 10. Assume the stunt double has a mass of 60kg and the force of gravity is −9.81m/s^2. Required:
Construct a differential equation which models the velocity of the falling stunt double. Explain the reasoning behind how you constructed the model you chose to use. Discuss any potential shortcomings of your model. Describe any initial conditions associated with your model.
