You have landed on an unknown planet, Newtonia, and want to know what objects will weigh there. You find that when a certain tool is pushed on a frictionless horizontal surface by a 12.3 N force, it moves 17.0 m in the first 2.50 s, starting from rest. You next observe that if you release this tool from rest at 10.8 m above the ground, it takes 2.88 s to reach the ground. What does the tool weigh on Newtonia? What would it weigh on Earth?
