Question

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 16.9 m in the first 2.40 s, starting from rest. You next observe that if you release this tool from rest at 11.0 m above the ground, it takes 2.78 s to reach the ground

Part A

What does the tool weigh on Newtonia?

Express your answer in newtons.

Part B

What would it weigh on Earth?

Express your answer in newtons.

Expert Solution

Step 1

Given :

On the horizontal surface-

Applied force, $F = 12.9 N$

moved distance, $s = 16.9 m$

time taken, $t = 2.40 s$

In the vertical direction :-

height, $h = 11 m$

time taken to reach the ground, $t' = 2.78 s$
