Force exerted by a golf club

  1. Mar 22, 2012 #1
    1. The problem statement, all variables and given/known data

    In a typical golf swing, the club is in contact with the ball for about .001s. If the 45g ball acquires a speed of 53 m/s, estimate the magnitude of the force exerted by the club on the ball.

    2. Relevant equations

    do i use a collision formula for this?

    3. The attempt at a solution

    pi=pf
    p1i+p2i=p1f+p2f
    vf=m1v1i/m1+m2

    Okay, let's step back a minute to our basic equation of motion;
    F=ma
    You want to solve for a force, so this would be the natural equation to use.
    Now, you know enough to solve for F, you know the mass and you can work out the acceleration from what you have!

    Using conservation of momentum is a handy thing to use but not in this kind of problem.

    so acceleration is rate of change of velocity over time so would i divide 53 by .001?

    That is correct!
