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...

Two boxes connected by a light horizontal rope are on a horizontal surface, as shown in the following figure. The coefficient of kinetic friction between each box and the surface is 0.30. One box (box B) has mass 4.84 kg , and the other box (box A) has mass m . A force F with magnitude 37.3 N and direction 53.1 ∘ above the horizontal is applied to the 4.84 kg box, and both boxes move to the right with...

A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.
Use the work-energy theorem to determine the speed v of...

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)...
