I think you mean velocity. There is only a downward acceleration (gravitational acceleration) for bodies in free-fall, and their acceleration would be the same. So I'm going to assume velocity.
Using the idea of conservation of momentum, when you swing a a golf club, there is momentum of F*dt. where F is the force and dt is the time of impact. Once you hit the ball, momentum is transferred. Another equation for momentum is m*v which is mass times velocity.
Modeling this we see:
F*dt = m*v
So the larger the mass, the smaller the velocity. Smaller the mass, the larger the velocity. That's why a golf ball's initial velocity is faster.
