hooke's law and shm help please
a 4 kg mass is placed on a spring (k = 40n/m) which hangs vertically. the mass is allowed to oscillate in shm. the maximum distance the mass travels in anyone direciton is 30cm
k = 40 n/m
distance = 30 cm
mass = 4 kg
Fspring = -kx
net force = Fspring-mg
Fspring = -kx
Fspring = -(40) (.3) = -12 (wrong answer)
