elastic rubber
Figured out the first part. Got stuck in the 2nd. I am confused whether the rubber string with exert some force similar to spring or not.

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.yes because it is written that rubber produces a force proportional to extension
but after a time it will slack, how do we deal with that. can u send the soln
it will be slack after reaching mean position
before that it should behave like normal spring i guess
@vj_25 apna solution bhejde
method toh samajh aagya but ek doubt hai mujhe kal karte time bhi aaya tha ki speed with which it hits lower one equilibrium position ki speed hai?
because if yes then it is coming out to be c which is the answer
but 5.1 speed toh uski 0.4m above ground par hogi
woh toh 1/2mv^2 = mgh + 1/2kx^2 se aa ja rha hai
idk man am confused as well
@Real potato @¹¹⁷sos any inputs?
Is it 5.1
yep
5.1 aa to rha h lekin wo tb ara h jab niche wli ball ko rest pr consider kr rha hu lekin uspe bhi force lgayega thread to wo bhi upar ayega
ball toh rest par hi hai neeche wali but it does have spring potential energy
Niche wli rest p kese
because woh just uthi hai ground se (am talking bout before releasing the upper ball)
Acha ha then it is correct
apna soln bhejdo pls
Isse ayega

Two tennis balls of mass 60 g`are attached with a massless rubber thread, and held in the vertical position as shown in the figure. In this position the unstretched length of the rubber thread is 40 cm. The upper ball is slowly raised vertically upward, until the lower ball just becomes unsupported by the ground. At this time the length of the t...
please check this and close the thread out :D
We good? did you check the video out?
