Benda bermassa m, = 30 kg diletakkan di atas benda yang bermassa m = 40 kg. Kemudian kedua benda tersebut didorong vertikal ke atas dengan gaya sebesar 280 N. Jika besar percepatan gravitasi g = 10 m/s- maka tentukan besar percepatan kedua benda dan juga gaya aksi-reaksi (gaya kontak) antara benda m1, dan m2.
