You are pulling your little sister on her sled across an icy (frictionless) surface. When you exert a constant horizontal force of 114 N, the sled has an acceleration of 2.3 m/s2 If the sled has a mass of 7.6 kg, what is the mass of your little sister?

I don't need the answer, just help on how to solve it. Thanks

  1. (m1+m2)a=F
    m1+m2 =F/a
    m2=F/a – m1
