N2: F=ma can be written as dv/dx=-gy-(bv/m)

g=grav. constant

b=constant where D(total drag force opposing dir. of

trav.)=-bv

y is simply y/vertical component

m=mass

I know dv/dt=a but what is dv/dx-working with the units I just got m^2s^-1. Sooo please can anyone enlighten me on this? Just started uni nd this is in lecture notes.

Ahh merci x x x
