Two forces of magnitude 50 N, as shown in the figure below (one at center, other in opposite direction at rim), act on a cylinder of radius 4 m and mass 6.25 kg. The cylinder, which is initially at rest, sits on a frictionless surface. After 1 second, the velocity and angular velocity of the cylinder in m/s and rad/s are respectively a.
Two masses, m1= 1.65 kg and m2= 3.30 kg, attached by a massless rod parallel to the inclined plane on which they both slide (see Figure 6.8), travel along the plane with m1trailing m2. The angle of incline is 30deg.. The coefficient of kinetic friction between m1and the incline is u1= 0.226; that between m2and the incline is u2= 0.113. Two blocks connected by a rope of negligible mass are being dragged by a horizontal force . F (Fig. P5.45). Suppose that F = 68.0 N, m1 = 12.0 kg, m2 = 18.0 kg, and the coefficient of kinetic friction between each block and the surface is 0.100. (a) Draw a free-body diagram for each block. The figure shows two boxes, with $m_1 > m_x$ that are on a level frictionless surface. We can apply a horizontal force $F$ either toward right on $m_1$ or toward left on $m_2$. The magnitude of the forces that the boxes exert on each other is. The answer is "larger if $F$ is applied toward the left...

Figure Il: After 8. A thin, uniform rod of mass Ml and length L , is initially at rest on a frictionless horizontal surface. The moment of inertia of the rod about its center of mass is (1/12)MIL2. As shown in Figure I, the rod is struck at point P by a mass m2 whose initial velocity v is perpendicular to the rod. After the collision, mass m2 has 5. A block of mass m1 = 20.0 kg is connected to a block of mass m2 = 35.0 kg by a massless string that passes over a light, frictionless pulley. The 35.0-kg block is connected to a spring that has negligible mass and a force constant of k = 222 N/m as shown in the figure below. The

The acronym for 'binary digit'; one of the digits (0 and 1) used in binary notation. 5. Tables often include abbreviations and technical words that are not easy to understand.
Since F is the only net force acting on the two masses, it determines the acceleration of both: The force F 2 acting on the smaller mass may now be determined. Note that by Newton's third law, the force F 2 acts backward on m 1. Note that the net force acting on m 1 is consistent with the above.
In the system shown above, the block of mass M1 is on a rough horizontal table. The string that attaches it to the block of mass M2 passes over a frictionless pulley of negligible mass. The coefficient of kinetic friction (k between M1 and the table is less than the coefficient of static friction (s. a.
