Newton's Laws: Impact, Orbit & Weight

AI Thread Summary
The discussion centers on Newton's laws of motion, particularly regarding the impact force between a bumble bee and a train, where the force experienced by both is equal due to the third law. Participants explore the centripetal force that keeps Earth in orbit around the sun, identifying gravity as the key factor. A calculation for the weight of a 76.0 kg person on Earth is discussed, with the correct weight being approximately 745.6 Newtons, not -744.8. Clarifications emphasize the importance of following homework guidelines when seeking assistance. Overall, the conversation highlights fundamental principles of physics related to motion and gravitational forces.

1. Which will have the greater force during impact; a bumble bee being hit by a train or a train being hit by a bumble bee? (Hint: Newton’s Three Laws of Motion)

1. What is the centripetal force that holds the Earth in orbit around the sun?

1. How much does a 76.0 kg person weigh on Earth in Newtons?

excuse me I have the answers that I think are correct just need a liitle more assistance
 
for the first question I assume they are equal
the second question I got gravity
the last one I got -744.8
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
