THE MODEL DIAGRAM THE EQUATIONS Displacement(t) = Displacement(t - dt) + (Rate_of_Change_of_Displacement) * dt INIT Displacement = 1.5 {m} Rate_of_Change_of_Displacement = Velocity Velocity(t) = Velocity(t - dt) + (Rate_of_Change_of_Velocity) * dt INIT Velocity = 0 {m/s} Rate_of_Change_of_Velocity = Acceleration Acceleration = Net_Force/Mass acceleration_due_to_gravity = -9.8 {m/s^2} air_density = 1.16 {kg/m^3} Applied_force = weight cross_sect_area = 0.0133 {m^2} drag = 0.5*drag_coefficient*air_density*cross_sect_area*Velocity^2 drag_coefficient = 1 Mass = 0.00105 {kg} Net_Force = Applied_force+Opposing_Force Opposing_Force = drag weight = Mass*acceleration_due_to_gravity
