Ratio Speed

AI Thread Summary

Two skaters with masses of 55 kg and 75 kg push off each other and move in opposite directions. To find the ratio of their speeds, the principle of conservation of momentum is applicable. The total momentum before and after the push must remain constant, implying that the momentum gained by one skater is equal to the momentum lost by the other. The kinetic energy formula, KE=0.5*m*v^2, is referenced but not directly applied in the solution attempt. The discussion highlights the need for a clearer understanding of momentum conservation to solve the problem effectively.

Homework Statement

Two skaters stand face to face. Skater 1 has a mass of 55 kg, and skater 2 has a mass of 75 kg. They push off one another and move in opposite directions. What is the ratio of skater 1's speed to skater 2's speed?

Homework Equations

KE=0.5*m*v^2

The Attempt at a Solution

Maybe the information in the problem is not enough... :( i don't know

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged 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...
