projectiles up an inclined plane

Daniel123 · 2008-12-09 05:57:27

Could someone very briefly explain the method involved in dealing with a projectile fired up an inclined plane? (i.e. how are velocities and weights resolved etc).

Quick responses would be greatly appreciated.

Thanks.

acceleration due to gravity would be resolved as (letting x be vector along plane, y being perpendicular to plane)

and if you have the velocity in terms of normal coordinates as (x,y) you'll have

is that what you meant?

What's theta?

angle of which the plane is elevated.

Yep, just bothered to actually think about this.

Thanks.

Although, I seem to get that the x component of the acceleration is -gsinθ?
