Applications of higher order differential equations
A spring has one of its ends fixed, and a force of 15 N stretches it 20cm. A mass of 4 Kg is attached to the end of the spring, and the system is set in motion with initial position = 60 cm and initial velocity = 1.5 m/s.
(a) Find the spring constant. (b) Write a problem of initial conditions for spring stretching, in meters. (c) Solve the problem posed in (b). (d) Write the solution in the form x = rsen(ωt + θ). (e) What are the amplitude, frequency and period of movement?
