i have a projectile that generated by this code:

//initial code  
bullet1.x = bullet1.x + (cur\_speed\_x / 10);  
bullet1.y = bullet1.y - (cur\_speed\_y / 10);  
cur\_speed\_y = cur\_speed\_y - g / 50;

//in a loop  
bullet1.x=x\_orig;  
bullet1.y=y\_orig;  
cur\_speed\_x=cur\_speed_Math.cos(angle_Math.PI/180);  
cur\_speed\_y=cur\_speed_Math.sin(angle_Math.PI/180);

i want the projectile to keep the same path but just move faster without having to increase the frame rate of the movie. anyone know where i should increase the motion in the above formulas to get that to happen?
