When a rope with mass m is dropped onto a scale from a stretched position, the maximum weight registered by the scale will depend on the dynamics of the rope's fall and the impact force. The force exerted on the scale will be influenced by the rope's mass, the acceleration due to gravity, and the speed at which the rope impacts the scale. The maximum weight can be calculated using principles of physics, including momentum and energy conservation. Participants are encouraged to show their calculations and specify where they encounter difficulties in solving the problem. Understanding these concepts is essential for accurately determining the scale's reading during the drop.

Rope with mass m is being dropped on a scale. What is the maximum weight the scale will register? Length of the rope is 1 and it is dropped from thee stretched out position.
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...
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
$$T + f_f - N_w = Ma$$

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
