    Jump Rebound
AI Thread Summary
To calculate the rebound distance in a bungee jumping scenario, it's essential to understand the rebound force and how it relates to the bungee cord's properties, such as the spring constant (k) and elongation. The maximum rebound height can be influenced by the damping coefficient of the bungee cord, which is not provided in the initial data. The original cord length is 17m, and the elongation is 23m, but the rebound height will also depend on the acceleration experienced when the cord retracts. Additionally, to avoid an obstacle 5m below the platform, calculations must consider the total distance fallen and the dynamics of the cord's retraction. A visual representation of the setup would aid in clarifying the calculations needed.

Hie all, curently i working on a mini project which require us to design a bungee jumping game where we had to decide all the data by myself.

here i got a few question want to ask n hope someone can help me a bit..
a) how to calcualte the rebound force and distance he will rebound??as i givin the k = 150 N/m, original cord length = 17m, elongation = 23m..n the distance between the platform and the ground = 45m.

b)if there is a obstacle is 5m from the platform, how to avoid it??

1. What do you mean by "rebound force" ? Please define this clearly.

2. There is not enough info to determine the rebound height. That is a function of the damping coefficient of the bungee cord, and the answer in the absence of damping will be the original height.
 
hie there..sorry for the unconvenient. I want to find out the maximum rebound height since i wil have a obstacle 5m below the jumping platform and need to avoid it. i know after the cord reach the maximum length, the cord wil retract to it's original length, which mean 17m. But when the cord retract, there is a acceleration.. so there is a force when the cord is retract.
 
It's hard to understand the question without a picture. Can you attach one ?
 

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 'Collision of a bullet on a rod-string system: query'

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'

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...
