Question #04a41 Physics 1D Motion Displacement and Velocity 1 Answer P dilip_k Aug 31, 2016 #"Total force applied on the system"=T# #"Total mass of the system"=m_1+m_2+m_3# #"Acceleration of the system"# #a=T/( m_1+m_2+m_3)# Tension in the string between #m_2 and m_3# will provide the same acceleration a in the combined mass # m_1+m_2# #"So the required tension"# #=(T( m_1+m_2)) /( m_1+m_2+m_3)# Answer link Related questions What is the difference between distance and displacement?
