RPinPA Thanks Charles, Yes, it's Φ = 3,5. The question is ''Find the 1st time when E=K.''

Homework Statement It's an oscillation problem. I have to find the FIRST time when the spring-mass system will have E (mechanical energy) = K (kinetic energy), if x(t)=12sin(5t+3,5). (t is time in seconds, x is lenghtof the system in cm). Homework Equations E=1/2kA^2 K= 1/2kx^2 The Attempt...
