1. The problem statement, all variables and given/known data 3. The attempt at a solution I'm at a complete loss here. Part A was simple enough, and I calculated a terminal velocity of 28 m/s for the ping pong ball and 34 m/s for the golf ball. But I don't even know how to begin Part B. Wikipedia says that Euler's Method is for solving ODE's, which I don't think is first-year material. In any case, I don't even see where time comes from in v(t), here's what I tried: Fnet = Fg + Fdrag ma = mg - 0.5pv2AC Then trying to figure time in somewhere: a = v/t mv/t = mg - 0.5pv2AC Then isolate v? Now i have a v(t) function I guess but i guarantee this isn't what I'm supposed to be doing! Please help!
