On the horizontal floor there are two boxes with masses m1 = 59 kg and m2 = 105 kg. The smaller box is pushed by 660 N. The smaller box pushes the larger box by 420 N. The smaller box acceleration is 2.5 m / s ^ 2 when the sliding coefficient between the box and the floor is 0.16. The situation remains the same, but the boxes exchange place.
a) Determine the acceleration a of the larger box.
b) Determine how much power a smaller box pushes a larger box in this situation.

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...

Three boxes, with masses m1, m2, m3 (kg) are stacked vertically; the bottom box is in contact with a rough floor and the surfaces between each box are also rough. An external force Fext (N) acts on the bottom box at an angle of XX degrees relative to the horizontal, as a result of which all three masses accelerate together with an acceleration a (m/s^2). a) Identify the number of forces acting on each box, b) starting with the top...

3) Two boxes sit on a horizontal table. Box 1 (m1 = 13 kg) is attached to box 2 (m2 = 34 kg) by a rope. You pull on a rope attached to box 2 with a force of 55 N. The coefficient of kinetic friction between both boxes and the table is 0.11 . (a) What is the acceleration of the boxes? (b) How far will the boxes move in 6.0 seconds? Assume they start from rest.
