# Projectile motion with varying air resistance

1. Apr 18, 2010

### tyuio2202

I've seen equations for projectile motion ignoring air resistance and how to solve for the equations of motion when a projectile experiences resistance proportional to its velocity, but how would you determine the equations of motion for a projectile when the air resistance is inversely proportional to the height of the object?

may= mg - bvy/ky
max = -bvx/ky

where the projectile has some initial velocity (v0) and angle of elevation ($$\theta$$)

but I don't know how one would go about solving for x(t) and y(t),
or if these equations would even be the way to go.

Can you offer guidance or do you also need help?
