Question: The 2520 Olympic and Paralympic games are celebrated in Omicron Persei 8 (a planet very far away from Earth). When landing after a spectacular somersault, a 42-kg gymnast decelerates by pushing straight down on the mat. If the gymnast is exerting a force of -1386 N on the ground which results in her deceleration to be 7 times the acceleration due to gravity of that planet, what is the magnitude of the constant of gravity in Omicron Persei 8? Express your answer in m/s2. Express your answer with three significant figures. Note for clarification: a somersault is an acrobatic exercise in which a person's body rotates 360? around a horizontal axis with the feet passing over the head.
