One Dimension Free-Fall Problem

AI Thread Summary
Hugh throws a ball upwards to hit Sue, who is 7.2 meters above him, timing it to reach her one second after passing her. The initial velocity (Vo) calculated by some participants is 16.66 m/s, but this value does not satisfy the position equation when tested. There is confusion among users regarding the calculations and the correct application of equations. Participants are seeking clarity and assistance to resolve the discrepancies in their findings. The discussion highlights the challenges in solving the free-fall problem accurately.

5. Sue is watching Hugh 7.2 meters below her when she sees him throw a ball up to hit her. She pulls in her head, but Hugh purposely threw the ball hard enough to hit her on his way down 1 second after it passes her on the way up. Explain how hugh figured this out...

I used a sort of system of equations...but it is comin out to 16.66 as the Vo, but when i plug it into the equation, it doesn't fit the other times

come on ya'll, i need some real help
 
woah EASYYYY on the help
 
this is the best help site EVVAR
 
everyone keep viewing and not helping, i keep gettin 16.66, EVERY WAY I TRY, but that doesn't fit the position equation correctly
 
16.66 for the initial velocity BY THE WAY

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 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...
