... hone in the next class, on drag. The first thing to pull out of this material is how to deal with the derivative of p=mv. The simple answer is that we apply the product rule: d/dt(mv)=m(dv/dt)+(dm/dt)v. In free space, where the net external force is zero, the total momentum of the rocket plus its ex ...

... Average speed is total distance over total time. It is measured in the same units as speed. 5. Define Velocity. What are its units? Velocity is rate of change of displacement. It is a vector and has both magnitude and direction. Example. 10 km/h due North, 30 m/s due South. 6. What is instantaneous ...

... Air Drag Problems Cont. Q: A skydiver jumps from a high flying helicopter. As she falls faster and faster through the air, does her acceleration increase, decrease, or remain the same? A: Acceleration decreases because the net force acting on her decreases. Net force is equal to her weight minus he ...
