Distance Homework: Find the Distance Travelled by Starship

AI Thread Summary
The discussion revolves around calculating the distance a Federation starship moves while pulling a shuttlecraft using a tractor beam. The starship has a mass of 1.90×10^6 kg, and the shuttlecraft weighs 2.00×10^4 kg, with the tractor beam exerting a constant force of 4.0 x 10^4 N. Participants highlight the importance of determining the center of mass for the two-ship system, noting that it affects how far each ship moves when the tractor beam is activated. The concept of action and reaction is emphasized, suggesting that the distance each ship travels is influenced by their initial positions before the tractor beam is engaged. Understanding these dynamics is crucial for solving the problem accurately.

Homework Statement



A Federation starship ( 1.90×10^6 kg) uses its tractor beam to pull a shuttlecraft ( 2.00×10^4 kg) aboard from a distance of 11.0 km away. The tractor beam exerts a constant force of 4.0 x 10^4 N on the shuttlecraft. Both spacecraft are initially at rest.

How far does the starship move as it pulls the shuttlecraft aboard?

Where is the center of mass of the two ship system?
 
It didn't specify in the problem.

Actually I was suggesting you figure it out.

When the tractor beam pulls the ship on board won't the center of mass then be in the middle of the mother ship?

By action reaction - no net external forces - how far each is before the tractor is switched on is how far they will travel then, right?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
