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 12.0 N force, it moves 16.4 m in the first 2.50 s, starting from rest. You next observe that if you release this tool from rest at 10.3 m above the ground, it takes 2.88 s to reach the ground. What does the tool weigh on Newtonia (in N)?What would it weigh on Earth (in N)?
Answers: 3
on the planet
on earth
force applied on the tool, 
displacement of the tool, 
time taken for the displacement, 
height of releasing the tool, 
time taken by the tool to fall on the ground,
