check this code

onClipEvent (load) {  
k = .2;  
damp = .9;  
grav = .1;  
}  
onClipEvent (enterFrame) {  
ax = (\_root.\_xmouse-\_x)\*k;  
ay = (\_root.\_ymouse-\_y)\*k;  
vx += ax;  
vy += ay;  
vy += grav;  
vx \*= damp;  
vy \*= damp;  
\_x += vx;  
\_y += vy;  
}

i got the solution…the actual code is:

onClipEvent (load) {  
k = .2;  
damp = .9;  
grav = .1;  
vx = 0;  
vy = 0;  
}  
onClipEvent (enterFrame) {  
ax = (\_root.\_xmouse-\_x)\*k;  
ay = (\_root.\_ymouse-\_y)\*k;  
vx += ax;  
vy += ay;  
vy += grav;  
vx \*= damp;  
vy \*= damp;  
\_x += vx;  
\_y += vy;  
}

LOL
