a man hits a golf ball (0.2kg) which accelerates at a rate of 20 m/s what amount of force acted on the ball

2 Answer

  • Force = mass * acceleration

    F = 0.2 * 20 = 4 Newtons

  • The ball only accelerates during the brief time that the club is in contact
    with it. After it leaves the club face, it takes off at a constant speed.

    If it accelerates at 20 m/s² during the hit, then

       Force = (mass) x (acceleration) = (0.2kg) x (20 m/s²) = 4 newtons .
