Asked by Camz

a 72N force accelerates mass m, by 5.0 m/s^2 the same force acts on another mass m2 and imparts to it an acceleration of 20.0 m/s^2. what acceleration will the same force impart to the two masses when they are joined?
Answered by Henry
F = M*a, M1 = F/a = 72/5 = 14.4 kg.

M2 = 5/20 * M1 = 5/20 * 14.4 kg = 3.6 kg

a = F/(M1+M2) = 72/(14.4+3.6) =
