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)...

4. Two blocks with masses 10.0 kg and 15.0 kg are placed on a horizontal frictionless surface. A light spring is placed in a horizontal position between the blocks. The blocks are pushed together, compressing the spring, and then release from rest. After blocks have lost contact with the spring, the 10.0 kg mass has velocity, v = 4.0 î m/s. (a) How much potential energy was stored in the spring before the blocks were released? (b) What is the...

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...
