1. The problem statement, all variables and given/known data A massless spring of spring constant k = 74 N/m is hanging from the ceiling. a 490 g mass is hooked onto the unstretched spring and allowed to drop. A) Find the amplitude B) Find the period of the resulting motion 2. Relevant equations f = 1/T F=-kx x(t) = Acos (omega) t omega = sqrt( k / m ) x(t) = Acos(omega * t + phi ) omega = sqrt ( g / L ) T = 2*PI * sqrt ( L / g ) 3. The attempt at a solution I'm lost in this chapter and have no idea where to start, i was curious if someone could help step me through this problem, would help me a ton. Thanks!!
