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 12.9 N force, it moves 16.8 m in the first 2.20 s, starting from rest. You next observe that if you release this tool from rest at 10.0 m above the ground, it takes 2.78 s to reach the ground. 1. What does the tool weigh on Newtonia? 2. What would it weigh on Earth?
