Question

A man hits a golf ball {mass=0.2kg}Which accelerates at the rate of 20m/sec2.What amount of force acted on the ball. {F=m x a}.

Answer 1

As, Force is mass times acceleration
$F=ma$

$F=0.2*20$

$F = 4N$

Answer 2

as we know the formula of force(F)=mass(m)x acceln(a)
given:- mass of ball=0.2kg
            accln of ball=20m/s2
  
force=mass x acceln
         = 0.2 x   20
          =2/10 x  20
           =4N

hope it helps...........
