A light rope passing over a frictionless pulley connects two objects. One object has a mass of 10kg. The tension in the rope is 90N. Calculate the acceleration and the mass of the second object.

Object 1
Fg-Ft = ma
100 - 90 - 10*a
10/10 = a
a = 1m/s^2

Object 2
Ft-Fg = ma
90-m10 = ma


I don't know what to do next. Help?
