1. The problem statement, all variables and given/known data

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 any one direciton is 30cm

2. Relevant equations

k = 40 n/m

distance = 30 cm

mass = 4 kg

Fspring = -kx

net force = Fspring-mg

3. The attempt at a solution

Fspring = -kx

Fspring = -(40) (.3) = -12 (wrong answer)
