A cart of mass 0.5kg is attached to a block of mass 0.9kg by a uniform rope that
passes over an ideal pulley fixed to the corner of a table, as shown in the diagram
above. The system is released from rest and the cart begins accelerating to the right
as the hanging block accelerates downwards. Assume the cart rolls with negligible
friction in its axles.
Calculate the acceleration of the cart. Round your answer to the nearest tenth.
