A man hits a golf ball (0.2 kg) which accelerates at a rate of 20 m/s2. What amount of force acted on the ball?

Sagot :

AL2006
Newton taught us that    Force = (mass) x (acceleration)

Force  =  (0.2) x (20) = 4 newtons .

Something to think about:  The ball can only accelerate while the club-face
is in contact with it.  Once the ball leaves the club, it can't accelerate any more,
because the force against it is gone.
