Some multi-body systems ask you to determine the unknown force of tension (Ft) in the cable connecting masses. This is done by determining the acceleration of the whole system as above
PLUS
Drawing an FBD of a single mass to which the cable is attached4)Finding Fnet (single body) using Newton's 2nd Law5)Finding the Ft using the definition of Fnet6)
Determine the tension in the cable connecting masses in each previous example.
