Free-Fall Homework: Find Velocity of Dropped First-Aid Kit

AI Thread Summary
The problem involves calculating the velocity of a first-aid kit dropped by a climber descending at 1.2 m/s after 4.2 seconds. The initial calculation of the kit's velocity is noted as -42.36 m/s, but the focus shifts to finding the distance the kit is below the climber after that time. The formula used, deltay = vit + 1/2at^2, is questioned for accuracy. A key point raised is the need to consider the distance the climber descended during the kit's fall. Understanding both the kit's drop and the climber's descent is essential for solving the problem correctly.

Homework Statement


A small first-aid kit is dropped by a rock
climber who is descending steadily at 1.2 m/s.
a) After 4.2 s, what is the velocity of the
first-aid kit? Answer in units of m/s.

Ok i know that the velocity after the 4.2 sec is -42.36 however the question asks how far is the kit below the climber after the 4.2 sec.
I tried using deltay=vit+1/2at^2 but it is wrong
can someone help me or tell me what is it iam doing wrong?
Thanks

Did you also account for the distance the climber descended while the kit was dropping?

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...
