1. The problem statement, all variables and given/known data Mars Data: Radius = .53 * Earth's Radius Mass = .11 * Earth's Mass Find the acceleration due to gravity on Mars in terms of g, the acceleration due to gravity on Earth. 2. Relevant equations g=Gm / r2 3. The attempt at a solution gm= G(.11 ME) / .53rE2 gE = GmE / rE2 9.8 m/s2= GmE / rE2 gM/gE gM=[G(.11 ME) / r2] / [GmE / rE2] * 9.8 gM= .11/.53 * 9.8 gM=2.034 m/s2 I'm not sure if this is right though.
