An ideal spring requires 50 J to be compressed by 15 cm.The value of the spring constant of this spring is

Question

Quizplus · Accepted Answer

The formula for the potential energy stored in a spring is:

U = 1/2 k x^2

where U is the potential energy stored, k is the spring constant, and x is the displacement of the spring from its equilibrium position.

Using the given information:

U = 50 J
x = 15 cm = 0.15 m

Substituting these values into the formula:

50 J = 1/2 k (0.15 m)^2

Solving for k:

k = 4444 N/m

Therefore, the answer is C.
