For the system on the diagram, the string is massless, and slides over the pulley without friction. The masses are m1 = 5.7kg and m2 = 6.4kg. what is the magnitude of the acceleration of the system is ( in m/s2)

assuming no friction, m1 is on a hoizontal, and m2 is vertical.

Forcepulling=m2*g=(m1+m2)a
solve for a.
