A 4kg mass sits on a surface with a coefficient of
friction of 0.47. The spring (spring constant = 140 N/m) is
compressed a distance of 0.62m from its unstretched position and
released. What is the velocity of the mass when the spring reaches
its unstretched position?

Question 2 A particle of mass m, is attached to a spring of natural length 2le and stiffness 2k, and a second spring of stiffness k and natural length lo. It lies on a smooth horizontal table. and the two spring ends are a fixed distance 4lo apart, as shown in Figure Q2. The particle is released from rest at a distance 2lo from each end. Let x be the distance of the particle from A wwwwwwwwww Figure 02 (a)...
The toy gun in the figure below consists of a spring with spring constant k. It is loaded with a projectile of mass m and the spring is compressed a distance d. The toy gun is fired horizontally and the bullet travels a total distance L within the toy gun before it is released. A) Neglecting all resistive forces, determine the speed of the projectile vo once it exits the toy gun (i.e., express Vo in terms of the known quantities...
8. A mass on the end of a string of length is displaced an angle from vertical and released (shown in the figure below). At the bottom of the swing the mass is released from the string and allowed to slide with friction coefficient uk) over a distance, d, before compressing a spring a distance, x (you may assume the friction only acts over the distance, d). CHEMISTRO IS BACK Use conservation of energy to find an equation for the...

Consider an ideal mass-spring-damper system similar to Figure 3.2. Find the damping coefficient of the system if a mass of 380 g is used in combination with a spring with stiffness k = 17 N/m and a period of 0.945 s. If the system is released from rest 5 cm from it's equilibrium point at to = 0 s, find the trajectory of the position of the mass-spring-damper from it's release until t 3s Figure 3.2: Mass-spring-damper...
Part A Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length lo- Another block B, having a mass mB, is pressed against A so that the spring deforms a distance d. The coefficient of kinetic friction between the blocks and the ground is μk. (Figure 1) Assuming separation does occur what is the distance the blocks slide on the surface before they separate? Express your answer in terms of some...
Block A, having a mass m, is released from rest falls a distance h and strikes the plate B having a mass 2m. If the coefficient of restitution between A and B is e, determine the velocity of the plate just after collision. The spring has a stiffness k.
k Problem 2 (30 pts) Blocks A and B are released from rest when the spring is unstretched. Block A has a mass my=3kg, and the linear spring has stiffness k=8N/m. If all sources of friction are negligible, determine the mass of block B such that it has a speed vp=1.5m/s after moving 1.2m downward, assuming that A never leaves the horizontal surface shown and the cord connecting A and B is inextensible. Use the work-energy principle. A B

6) A mass-spring system consists of a 250-g mass hanging from a spring with a spring constant of k 0.18 J/m2. The mass is pulled down 7.1 cm from its equilibrium position and released from re a) How much work did the person do when she pulled the spring down from its equilibrium position? Assume that the mass was at rest before she pulled it down, and before it was released. (Use the energy-interaction model, not the expression W FavgAx,...
