An object with a mass of #7 kg# is hanging from a spring with a constant of #3 (kg)/s^2#. If the spring is stretched by # 1 m#, what is the net force on the object? Physics Forces and Newton's Laws Newton's Second Law 1 Answer 1s2s2p May 14, 2018 #71.67~~71.7~~71~~70N# (choose whichever seems more appropriate) Explanation: #SigmaF=F_s+F_l# #F_l=mg=7*9.81=68.86N# #F_s=kDeltax=5*1=3N# #SigmaF=68.67+3=71.67N# Answer link Related questions What are some common mistakes students make with Newton's second law?
