Homework Help: Question on impulse, does it assume elastic collision?

  1. Apr 16, 2008 #1
    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?
