Two blocks of masses m, = 6.0 kg and m2 = 12 kg are connected with a string that passes over a very light pulley (Figure 1). Friction in the pulley can be ignored. Block 1 is resting on a rough table and block 2 is hanging over the edge. The coefficlent of friction between the block 1 and the table is 0.70 (assume static and kinetic friction have the same value). Block 1 is also connected to a spring with a constant 300 N/m. In the initial state, the spring is relaxed as a person is holding block 2, but the string is still taut. When block 2 is released, it moves down for a distance d until it stops (the final state).

A particle with a mass of = 3 kg is connected to a spring and it slides on a smooth horizontal surface. The spring’s unstretched length is h = 100 mm. The spring is connected at point O. The velocity of the particle at position A has a magnitude vA = 4 m/s and makes an angle of 54° with the spring at that instant. The velocity of the particle at position B makes an angle of 65° with the spring at that later instant. a) Determine the angular momentum (Ho)A of the particle about point O at position A. b) Find the magnitude vB of the particle’s velocity at position B. c) Determine the springs stiffness k.
There is a block that weighs 2.0 kg block and is sitting on a surface with which it has a coefficient of static friction of 0.7. A spring with spring constant 33 N/m is attached to the block. You pull slowly on the spring, stretching it out. How long does the spring get before the block starts to slide?

A mass is attached to a spring and allowed to hang vertically from a fixed support. The spring naturally stretches to position A. The mass is then pulled down to position B and released. The mass then vibrates up and down in periodic fashion. How does the velocity and acceleration compare E F O Max Velocity D, Max Acceleration E O Max Velocity G, Max Acceleration C Max Velocity F, Max Acceleration D O Max Velocity E, Max Acceleration F 0000000 0000000
A spring with a spring constant of k = 192 N/m is initially compressed by a block a distance d = 0.23 m. The block is on a horizontal surface with coefficient of kinetic friction μk, static friction μs, and has a mass of m = 7 kg. How large would the coefficient of static friction μs need to be to keep the block from moving? Recall that to keep the block from moving, the acceleration is zero. Assuming the block has just begun to move and the coefficient of kinetic friction is μk = 0.2, what is the block's acceleration in meters per square second?
Imagine you've constructed a pendulum at home and measured the length of the rope and the period. The goal here is to create a graph where the slope corresponds to the gravitational acceleration constant. For that you have to get an X and a Y. First, you have these 2 equations as a starting point: T= 2π/ω and ω= sqrt(g/L). Play with the equations to construct an equation for a linear graph with the form: Y=mX+b where the slope m=g. Identify clearly what X and Y represent. The equation should look like: ? = g(? + ?)
A box of mass m = 0.36 kg is set against a spring with a spring constant of k1 = 694 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 278 N/m. The box is not connected to the first spring and may slide freely. 1. Now assume friction is present on the surface in between the ends of the springs at their equilibrium lengths, and the coefficient of kinetic friction is μk = 0.5. If the distance between the springs is x = 1 m, how far d2, in meters, will the second spring now compress?
In 0.450 s, an 7.00-kg block is pulled through a distance of 3.00 m on a horizontal frictionless surface, starting from rest. The block has a constant acceleration and is pulled by means of a horizontal spring that is attached to the block. The spring has a spring constant of 480 N/m. By how much does the spring stretch as the block is being pulled? i m

Not all "springs" are described well by Hooke's law; Hooke's law is a "first order" approximation. Say that a spring exerts a force F that is the following function of displacement: x=xi Please see the image below for the rest of the problem and answer choices.
