Simple Gravity Problem: Finding an Object's Maximum Height

AI Thread Summary
To determine the time it takes for an object thrown straight up to reach its maximum height, the relevant physics equation involves the acceleration due to gravity, g, set at 10 m/s². The object rises to a height of 80 m, and the time to reach maximum height can be calculated using the formula t = v/g, where v is the initial velocity. The user expresses frustration over a mental block, initially calculating 8 seconds, which is incorrect as it likely includes the return time to the original height. Clarification is needed to ensure the calculation focuses solely on the ascent to maximum height.

Homework Statement



An object is thrown strait up. It rises 80m and falls back to its original height. Take the object's original height as the origin and use g=10m/s^2.

How long does it take the object to reach its max height?


Homework Equations





The Attempt at a Solution



I learned this in physics 1 and I feel destroying my dorm room because I know how to do this but I am having a complete mental block and can't seem to do anything with this. I am getting 8s but that can't be right because it does not fit on the graph I need to graph the problem on.

Are you sure you're solving only for the max height? Or did you solve for the time the object returned to its original height?
 

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...
