A cube of mass m1 = 5.1 kg is sitting on top of another cube of the same size and mass m2 = 1.4 kg while they are both in free-fall. Ignoring any air resistance, what is the magnitude of the normal force with which the bottom cube is acting on the top cube?
Homework Answers
since both are having a free fall so net weight felt by any of the cube will be zero
hence no normal force by any cubes on any one
hence normal force=0 N

5. Two crates, with masses m1 = 83 kg and m2 = 210 kg, are sitting side-by-side and at rest on a horizontal surface (they are touching). A 750-N force is exerted on m1 so that the boxes both move in the same direction. If the coefficient of kinetic friction between the boxes and the table is 0.12, find: (a) the acceleration of the boxes and (b) the contact force the boxes exert on one other. 6. A raindrop falls...
