Find velocity at a specific time?

AI Thread Summary
To find the velocity at a specific time, it's essential to understand the motion of the mailbag, including its initial height and velocity. The problem involves calculating the time it takes for the mailbag to reach the ground after being released. Key factors include the effects of gravity and any initial conditions provided in the problem. For part (c), determining the time until the mailbag hits the ground requires applying kinematic equations. Understanding these concepts will help solve both parts of the question effectively.

Hey guys. I need help figuring out how to do this problem. I have a test tomorrow and i am currently studying. I would like to know how they got this answer. I'm completely stumped and need help so thanks in advance!

Here is the question:

Also, if not too much trouble can you help me with part c to this problem?:

(c) How long after it's release does the mailbag reach the ground?

What do you think, how does the mailbag move? At what hight does it start? What is its initial velocity?

Thread 'Errors and significant figures'

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 '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...
