Review Constants Let's begin with a straightforward example of simple harmonic motion (SHM). A spring is mounted horizontally on an air track as in (Figure 1), with the left end held stationary. We attach a spring balance to the free end of the spring, pull toward the right, and measure the elongation. We determine that the stretching force is proportional to the displacement and that a force of 60 N causes an elongation of 0.030 m. We remove the spring...
A 2.00-kg object is free to slide on a horizontal surface. The object is attached to a spring of spring constant 300 N/m , and the other end of the spring is attached to a wall. The object is pulled in the direction away from the wall until the spring is stretched 50.0 mm from its relaxed position. The object is not released from rest, but is instead given an initial velocity of 2.50 m/s away from the wall. Ignore...
A spring with k=130.0 N/m on surface is mounted to a vertical wall. A 5.00-kg box on the surface is placed in front of the spring. The coefficient of kinetic friction between the box and the surface is ylik = 0.400. A constant force F is applied to the box. F has magnitude 89.0 N and is directed against the wall. The spring is compressed 80.0 cm. Problem 5 Express your answer with the appropriate units. A spring with k=130.0...
One end of a light spring with force constant 240 N/m is attached to a vertical wall. A light string is tied to the other end of the horizontal spring. As shown in the following figure, the string changes from horizontal to vertical as it passes over a solid pulley of mass M in the shape of a solid disk of radius R 2.50 cm. The pulley is free to turn on a fixed smooth axle. The vertical section of...
A spring is hing from a ceil ing, and an object attached to its ower end stretches the spring tbr a distauce d . 5.00 cm from its unstretched pusition wheu the system in in equilibrium as in Figure P13.5. If the spring constant is The period of motion of an object-spring system is T= 0.528 s when an object of mass m- 238 g is attached to the spring. Find (a) the frequency of motion in hertz and (b)...
An object is suspended from the ceiling by a spring aligned along a vertical x axis, with upward defined as the positive x direction. When the spring is at its relaxed length, the object is at the origin of the axis. The object is pulled down to position −x1, held at rest, and released. Consider its motion from the instant of release until the instant it returns to −x1. Ignore friction, air drag, and the inertia of the spring. part...
One end of a light spring with force constant 290 N/m is attached to a vertical wall. A light string is tied to the other end of the horizontal spring. As shown in the following figure, the string changes from horizontal to vertical as it passes over a solid pulley of mass Mi the shape of a solid disk of radius R = 1.50 cm. The pulley is free to turn on a fixed smooth axle. The vertical section of...
A horizontal spring with k = 72 N/m has one end attached to a wall and the other end free. An 91 g wad of putty is thrown horizontally at 3.4 m/s directly toward the free end. Find the maximum spring compression (ignore gravity). Hint: Kinetic energy is converted into potentail energy of spring . Express your answer to two significant figures and include the appropriate units.
A mass of m kilograams (kg) is mounted on top of a vertical spring. The spring is L metres long when disengaged and the end not attached to the mass is fixced to the ground. The mass moves vertically up and down, acted on by gravity, the restoring force T of the spring and the damping force R due to friction: see the diagram below The gravitational force is mg dowswards, where g- 9.8m is acceleration due to gravity, measured...
3. A 20 cm long horizontal spring (k= 200 N/m) is attached to a wall. A 2 kg box is attached to the other end. You pull the box 3 cm, displacing the spring from equilibrium. Assume the floor is frictionless. a. If the box is released from rest at t = 0 s: i. Write an equation describing the position of the box at some arbitrary time "t". Go ahead and fill in the values for amplitude, phase angle,...
