Simple "what is velocity at time t" problem
A helicopter is lifting off. The only forces are air (up) and gravity. What is the vertical speed at time t if it took off at time t=0?
g = F(air)/m, g=Δv/Δt
F(air)/m = Δv/Δt
v = tF(air)/m, but I'm told that this is wrong. I believe I need to include g. What am I missing?
