Question

Three boxes, A, B, and C, are placed on a frictionless surface as shown in the diagram below. If you push on box A with a force of 8.25 N, find the contact force (in N) between each pair of boxes. Here m_A = 6.90 kg, m_B = 3.40 kg, and m_C = 1.50 kg. contact force between A and B contact force between B and C

00:01 Hi guys, now in this column, three boxes a, b, c are placed on a frictionless surface.
00:05 This is three boxes a, b and c.
00:09 This is a, this one is b, this one is c.
00:16 Now this is a, b and c.
00:22 Or i'm going to just say this is c, a and b.
00:27 This is c, b and a.
00:31 We apply a force of what? if you push a box b with a force of 8 .25 newton, this force is what 8 .25 newton.
00:46 So the question is, we need to find a magnitude of the contact forces between each pair of the boxes.
00:54 Now this is m of a is given to us.
00:56 This is 6 .8 kz...
