In each of the cases shown in the figure, the block has been displaced by the same amount from equilibrium. rank the cases based on the elastic potential energy stored in the springs.

case4 > case 2 > case 5 > case 3 >case 1

Explanation:

if displacement is same for all, then potential energy PE depends on k

case 1)

K1 = k * 2k / (k+2k) =2k/3  (due to series combination of them)

case 2)

K2 =k+k =2k  9 (due to parallel combination of them)

case 3)

K3 =k  (single body)

case 4)

K4 =(k*k/2k)+ 2k =k/2 +2k = 5k/2

(due to both series combination of the first two and parallel combination of the last)

case 5)

K5 =(k+2k)*3k/(k+2k+3k) = 3k/2

(due to the parallel combination of k and 2k and then a series combination with 3k)

Hence, the order of PE from greatest to lowest

case4 > case 2 > case 5 > case 3 >case 1

terd muffin is the correct answer

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
