Problem A vertical oscillating system consist of three equal springs with elasticity coefficient c , among which a mass m=2kg is suspended.The system oscillates according to the following law of motion x(t)=0,4 cos 4t+0,5 sin 4t , (m) . Determine: 1) The equivalent elasticity coefficient ce of reduced spring. 2) For t=0 values for initial conditions x0 and v0 3) The natural frequency k 4) The oscillation period T 5) The amplitude A Note = Please some help. I am high school student .Give me tips then i will try. Thanks to who helps.
