lingshot, which can be modeled as a spring with spring constant k = 81.9 N/m, is stretched by 22 cm with respect to its equilibrium position and used to shoot a k with mass 0.09 kg straight up into the air. Find the speed of the rock (in m/s) when it reaches a height which is 25% of its maximum height (relative to the sition at which it was shot from). Use g = 9.81 m/s?. Hint: First find the maximum height, and then find the speed when the height is 25% of that.

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 28-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, her kinetic energy decreases to 220 J from 420 J. How high does she rise during this interval? Neglect air resistance.
A simple pendulum consists of a 0.8- kg bob connected to a massless inextensible cord with a length L = 1.9 m. The bob is set into motion and its angular displacement is given by e(t) = 0.11cos(wt), where e is in radians and t is in seconds. Take g = 9.8 m/s^2, determine the mechanical energy of this pendulum.

Consider the mass-on-a-spring system as shown in the figure below. The spring has a spring constant of 1.86e+3 N/m, and the block has a mass of 1.39 kg. There is a constant force of kinetic friction between the mass and the floor of 4.71 N. Starting with the spring compressed by 0.117 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at the spring's equilibrium position, marked x=0 in the figure. Give your answer as the distance from the equilibrium position to the final position of the block.) Hint: How much work must friction do in order to bring the mass to a stop?

Two masses with mass mA = 3.051 kg and mB = 21.09 kg, respectively, hang with a massless rope over a homogeneous pulley with mass mC = 40.4 kg. The mass center of the pulley is located in the middle of the pulley. The pulley is attached with a frictionless bearing in the middle. g = 9,806 m/s². Calculate the upward force with which the line affects mass B if the pulley is a homogeneous circular disc with a radius of 0.444 m.
