Question on impulse, does it assume elastic collision?

A problem I am working on for a project....
Force required to hit a golf ball 76.2 m/s
Does the impulse assume the collision is perfectly elastic?

I am doing a problem on golf...

mass of golf ball .0459 kg
velocity of ball is 76.2 m/s
time of interaction is .0005 seconds
coefficient of restitution is .65 (how efficient the collision is)



impulse - F(∆t)



F=6998 N
but would the force actually be 10766N (6998/.65) since the coefficient of restitution is .65?
