Find velocity of a moment before terminal velocity is reached?

AI Thread Summary
The discussion centers on calculating the acceleration of a sky diver at specific velocities before reaching terminal velocity. The first part involves determining the acceleration when the diver's velocity is 39 m/s, with the calculated answer being approximately 5.0468 m/s². The second part presents a more complex scenario where the diver has a velocity of 34.2 m/s at a 56° angle below horizontal, prompting a request for guidance on how to approach this calculation. Participants are encouraged to share their working to clarify the initial answer and assist with the second scenario. The thread highlights the need for clear problem-solving steps in physics calculations.

Homework Statement


Given g = 9.8 m/s
2
.
A sky diver of mass 69 kg jumps from a
slowly moving aircraft and eventually reachesher terminal velocity 56 m/s.
What was (the magnitude of) her acceleration at the moment her velocity was only
v1 = 39 m/s (directed vertically down)?
Answer in units of m/s2
I got the answer to this as 5.0468


Now consider the same sky diver jumping out
of a faster airplane. At some point before she
reaches her terminal velocity, she has velocity
~v2 of magnitude 34.2 m/s in the direction 56◦
below hirizontal.
What is the magnitude of the sky diver’s
acceleration at that point in time?
Answer in units of m/s2

i have no idea how to do this one. Can someone show me how or point me in the right direction

Is there something missing here ↑↑↑ perhaps due to mis-editing?

Can you show your working so we can see how you did it? I don't get that answer.
 
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 '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...
