    A ball of mass 150 g, moving with an acceleration \[20\,m/{{s}^{2}},\]is hit by a force, which acts on it for 0.1 sec. The impulsive force is

    A) 0.5 N   

    B)        0.1 N

    C)  0.3 N  

    D)        1.2 N

    Correct Answer: C

    Solution :

    [c]  Mass\[=150\,gm=\frac{150}{1000}kg\] Force = Mass \[\times \] acceleration \[=\frac{150}{1000}\times 20N=3\,N\] Impulsive force\[=F.\Delta t=3\times 0.1=0.3\,\,N\]
