A mass-less spring having a spring constant k = 185 N/m, is inside a horizontal barrel. Its left end is rigidly fixed at position x = 0.0 cm, and its right end is at X = L, where L = 19.7 cm. The spring is then squeezed so that the right end of the spring is at X = S, where S = 13 cm. A ball of mass 50 g is put in front of the spring, and the spring is released. Calculate the speed of the ball (in m/s) as it comes out of the barrel. Ignore friction inside the barrel. X = 0.0 cm X = Lcm Equilibrium Position Squeezed Position X 0.0 cm X =S cm

Please could I have the solutions for this question in a step-by-step form. Thank you very much.
In the figure, we must apply a force of magnitude 83.0 N to hold the block stationary at x = -3.00 cm. From that position, we then slowly move the block so that our force does +4.00 J of work on the spring-block system; the block is then again stationary. What are the block's positions?

A shaft having length equal to 10 m and diameter equal to (50+ 16) mm is simply supported at both ends. The shaft carries four masses (150 + 16) kg, (200 + 16) kg, (250 + 16) kg and (300 + 16) kg. These masses are located at a distance of 1.5 m, 2.5 m, 5.5 m and 7.5 m from the left hand side support, respectively. The modulus of elasticity, E, for the material of the shaft is 200 GN/m2 and mass density for the shaft material is 7500 kg/m3. Determine critical speed of the shaft in revolutions per minute for the following two cases: Effect of the mass of the shaft is neglected. Effect of the mass of the shaft is considered. What is the usefulness of the answers determined in this problem?

Determine the instantaneous stress and elongation of a 30 mm diameter bar if a mass of 60 kg falls through a height of 60 mm on to a collar which is rigidly attached to the bottom end of the bar as shown in Figure Q2. The bar is 1.2 m long and is suspended vertically. The Modulus of elasticity, E, for the material of bar is 210 GPa. Take g = 10 m/s2.
There is a spring-mass system, driven by an external piston, which applies a force to it. Newtons that satisfies the following relation F = 6*cos (3*π*t), as can be seen in the figure, it is known that the spring constant has a value of k = 25 Nm, and the block has a mass of 4 kg, furthermore, dissipative frictional effects cause the relationship between velocity and force to satisfy the ratio F = bv, where b is the damping constant, and it is known that the numerical ratio of force is 10 times the value of speed. Determine: a) The natural frequency of the system. b) The driving frequency of the external force. c) The maximum value exerted by the external force. d) The damping constant. e) The amplitude of the forced oscillatory motion in steady state. f) If dissipative (damping) effects are neglected, what is the value of the amplitude.
A 0.1 m 0.3 m The pendulum shown consists of a slender rod with mass per unit length of 2.8 kg/m, and a thin plate with mass per unit area of 10.0 kg/m2. In the figure, L = 1.7 m.
A uniform board has a length L = 4.0 m and rests horizontally and somewhat above the ground on two cylinders of wood, each supporting the board at a distance of D= 0.75 m from the corresponding end of the board. (The axis of each cylinder is perpendicular to the length of the board.) The board has a mass of ma = 40 kg. A person with a mass of me = 50 kg is about to step on one end of the board. Our goal is to identify if it is safe for the person to step on the board. A. On the diagram below, draw all the forces acting on the board. Assume the person has just stepped on the left end. B. Each of the two wodden cylinders exerts an upward force on the board. Which one of those two forces is larger? If this detail is not evident from your force diagram, redraw it. C. If the board does end up starting to tilt after the person steps on it, what does that imply about the normal force that the right support exerts? D. Is it safe for the person to step on the board?
