text: a certain force applied to a 2kg mass accelerates the mass at 3m/s^2 how much acceleraton will the same? force produce on a 4-kg mass force applied on the 2kg mass = m x a = 2 x 3 = 6n  force applied on 4kg = force applied on 2kg mass                          m x a = 6n                          4 x a = 6                          a = 6 / 4 = 1.5 m/s^2  therefore, the acceleration produced on 4kg mass is 1.5 m/s^2
