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...

A block of mass m1 = 1.95 kg and a block of mass m2 = 5.50 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of θ = 30.0° as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks. A wedge in the shape of a right trapezoid...

2. Atwood's Table with Two Hanging Masses You have table of width L, masses m1, m2, and m3, two frictionless pulleys, and ideal string. Placing m2 on the table, you attach a bit of string to mass m1 the left pulley, to the left side of m2. Similarly, you hang mass m3 from the right side of m2 using the pulley on the right side of the table. The coefficient of friction of the table is mu. The acceleration of...
