- 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?arrow_forwardA 68.5 kg person is standing inside an elevator. The elevator is going from the 1st floor to the 9th floor.

What is the initial acceleration of the rocket, assuming you can neglect air resistance? 7.6 m/s² 15.2 m/s² 50.0 m/s² 25.0 m/s² QUESTION 4 Same rocket as in the previous question. After the rocket has been in flight for a while, having burned and exhausted 80,000 kg of propellant, its acceleration has reached 25.0 m/s². All this while the thrust has been constant at 5.00 x 106 N. What is the magnitude of the drag force (that is, the resistance from the air) at this point? Note that at this point the rocket's altitude is still low, so you can still take gravity to be g = 9.81 m/s2 3.00 x 106 N 5.00 x 106 N 1.18 x 106 N 8.23 x 105 Narrow_forward
