    Newton's Law's Problem (Contact Force)

    and to find acceleration, i would use the formula, F/mg which is 644/28, 644/18.8, 644/28.7?

    Newton's Law's Problem (Contact Force)

    Basically 3 boxes, somehting like this; Masses are as followed: M1= 28 kg, M2= 18.7 kg, M3= 28.7 kg. The applied force on the box is 644 N Part A) What is the magnitude of the contact force between M1 and M2 Part B) What is the magnitude of the contact force between M2 and M3 To find...
