Given that:

  • the velocity of AA with respect to CC, vAC=300 m/sv_{AC} = \text{300 m/s}\uparrow (note the direction of the velocity)
  • the velocity of BB with respect to AA, vBA=200 m/sv_{BA} = \text{200 m/s}\downarrow.

Find the absolute velocity of AA, vAv_A.


  • The strings are massless and inextensible.
  • The pulleys are massless and there is no friction in the pulley and between the string and pulley.
