AI Thread Summary
In an elastic collision between a small mosquito and a massive dinosaur moving at 2.62 m/s, the mosquito's speed after bouncing off is not simply equal to the dinosaur's speed. The discussion highlights the importance of considering mass in momentum equations, as the mosquito's negligible mass affects the outcome. Participants are seeking clarification on the correct application of momentum equations to determine the mosquito's speed post-collision. The conversation emphasizes the need for specific mass values to accurately solve the problem. Understanding these dynamics is crucial for correctly analyzing elastic collisions.

Homework Statement



A small mosquito is hovering in the air when a fast and massive dinosaur charges right into it with a speed of 2.62 m/s. If the collision is elastic what is the speed of the mosquito when it bounces off of the dinosaur.


Homework Equations



momentum equation


The Attempt at a Solution



Well since the don't specify the masses I just assume a tiny mass being hit by a massive one. The horizontal speed of the mosquito is 0 and the speed of the dinosaur is 2.62 m/s. I thought it would just be the same speed of the dinosaur (or slightlyyy larger) but this is wrong. Can someone please help?

Thank you very much

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'

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...
