Calculating Stone Distance and Speed: Kinematics Problem Help

AI Thread Summary
To solve the kinematics problem, first calculate the time it takes for the second stone to reach a speed of 11.0 m/s, which involves using the equation for velocity under constant acceleration due to gravity. Once the time is determined, find the displacement of the first stone during that time, which was calculated as 6.17 m. Then, use the time difference of 1.50 seconds to determine the displacement of the second stone at that moment. The key is to set up the equations correctly for both stones to find their respective distances. This approach will help in accurately determining how far apart the stones are at the specified speed.

Homework Statement



A stone is dropped from the roof of a high building. A second stone is dropped 1.50 s later. How far apart are the stones when the second one has reached a speed of 11.0 m/s?

Well, work out the displacement of the first stone when it reaches 11m/s, then the displacement of the second stone at this time.
 
i got the displacement of the first one as 6.17 m how do i get the second one?
 
There's no way I can tell you you're right or not if I don't see your work! Try calculating the time when the stone reaches 11m/s. Then you can perhaps find the displacement of the second stone at this time.

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 '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...
