Question
Two boxes sit side-by-side on a smooth horizontal surface. Thelighter box has a mass of 5.21 kg, the heavier box has a mass of7.16 kg.Calculate the contact force between these boxes when a horizontalforce of 5.18 N is applied to the light box. Calculate the contact force if the 5.18 N force isapplied to the heavy box instead.

Explanation / Answer
a = F/ (m1 + m2) a = 5.18 N / (5.21 kg + 7.16 kg) a = .419 Part a. Fcontact = mlarge x a F = 7.16 kg x .419 F = 2.998 N Part B. Fcontact = msmall x a F = 5.21 kg x .419 F = .175 N
