3/138 The 25-kg slider in the position shown has an initial velocity vo= 0.6 m/s on the inclined rail and slides under the influence of gravity and friction. The co- efficient of kinetic friction between the slider and the rail is 0.5. Calculate the velocity of the slider as it passes the position for which the spring is com- pressed a distance x = 100 mm. The spring offers a compressive resistance C and is known as a "hard- ening" spring, since its stiffness increases with de- flection as shown in the accompanying graph. 1 m = 0.6 m/s 60° 25 kg = 0.5 Hk= C, KN Problem 3/138 x, m 62x2 ✓ 18x
The pulley in Fig has radius R and a moment of inertia I. The rope does not slip over the pulley, and the pulley spins on a frictionless axle. The coefficient of kinetic friction between block A and the tabletop is mk . The system is released from rest, and block B descends. Block A has mass mA and block B has mass mB . Use energy methods to calculate the speed of block B as a function of the distance d that it has descended.
In the figure, m₁ = 12.0 kg, and α = 35.5°. The coefficient of kinetic friction between the block of mass m₁ and the incline is μk = 0.30. What must be the mass m₂ of the hanging block if it is to descent 8.0 m in the first 4.00 s after the system is released from rest? (15 points) Figure 3
3/72 The small object is placed on the inner surface of the conical dish at the radius shown. If the coefficient of static friction between the object and the conical sur- face is 0.30, for what range of angular velocities w about the vertical axis will the block remain on the dish without slipping? Assume that speed changes are made slowly so that any angular acceleration may be neglected. (0 0.2 m m 30° CamScanner Lino izowall

Learning Goal: In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: • First law: A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force. Second law: A particle acted upon by an unbalanced force, F experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force.
