  • Using Newton's second law of motion:

    F=ma ;  [ F = force (N: kgm/s^2);m= mass (kg); a = acceleration (m/s^2)


    Given:                      Find:                   Formula:                  Solve for m:

    F: 2500N                 mass:?                F=ma Eq.1              m=F/a  Eq. 2

    a= 200m/s^2  


    Solution:

    Using Eq.2

    m= (2500 kgm/s^2)/ (200m/s^2) = 12.5 kg
