. Terminal velocity - free fall. Estimate (order of magnitude) the terminal speed vT of a typical human in free fall. Draw a free body diagram for the person falling at terminal velocity. Use the FBD, Newton’s second law, and the formula for air resistance (drag force) mentioned in class FD = 1/2 D ρ A v2 to find an expression for vT . Explain/justify any assumptions that you make (e.g., for quantities like the cross-sectional area A or the mass m). You may estimate the drag coefficient D to be equal to one. Write the terminal speed in MKS units and miles per hour.

    1.  A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a)   What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b)   After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

    this project discovers the free-falling velocity of skydivers before the parachutes are opened using the laws of physics and calculus. you can ignore the wind in the horizontal direction. let m be the mass of a skydiver and the equipment, g be the acceleration due to gravity. the free-falling velocity of a skydiver, v(t), increases with time. the force due to the air resistance is correlated with the velocity, that is, Fr=kv^2, where k>0 if called the drag constant related...
