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 16.7 m in the first 2.30 5, starting trom rest. You next observe that if you release this tool from rest at 10.0 In above the ground, it takes 2.88 s to reach the ground. IO 7 PartA What does the tool weigh on Newtonia?
