Question 4 (30 points) Consider a block of mass m attached with a spring of stiffness k that oscillates in a horizontal surface (Figure 1A). The coefficient of static friction between the mass and the surface is c. The response of the system spring-mass to a step input of magnitude 6 × 10³N is illustrated in Figure 1B. Using the equation of motion, you need to estimate the values of the mass m, stiffness k and friction c.

A 1/5 kg mass is attached to a spring with stiffness k = 50 N/m. The motion is initiated by striking the mass, at equilibrium, so as to impart a velocity of 5 m/s to the right. Find the equation of motion if any damping, external forces and friction over the sliding surface, are ignored. Identify the amplitude and period of the oscillations. After how many seconds will the mass first cross the equilibrium point? Equilibrium point Figure 4.1 Damped mass–spring oscillator

A mass of 5 kg stretches a spring 10 cm. The mass is acted on by an external force of 10 sin(θ) N (newtons) and moves in a medium that imparts a viscous force of 2 N when the speed of the mass is 4 cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 3 cm/s, formulate the initial value problem describing the motion of the mass. Then (a) Find the solution of the initial value problem in Problem 6. (b) Identify the transient and steady state parts of the solution. (c) Plot the graph of the steady state solution. If the given external force is replaced by a force of 2 cos(ωt) of frequency ω, find the value of ω for which the amplitude of the forced response is maximum.

Q4) An object with mass M starts it motion from point A with an initial velocity V0 = 10 m/s on an inclined plane with a kinetic friction constant μ= 0.1, as shown in Figure. The object causes a maximum compression Δx on the spring having a spring constant k= 1 N/m, where the horizontal surface has no friction (g= 10 m/s²). a) (10 Pts.) Drawing the free body diagram, find the objects velocity at point B b) (15 Pts.) Find the amount of maximum compression Δx.
