Answer:

the maximum height reached by the marble is 11.84 m.

Step-by-step explanation:

Given;

mass of the marble, m = 0.02 kg

extension of the string, x = 0.08 m

force applied to the string, F = 58 N

Apply the principle of conservation of energy;

elastic potential energy = gravitational potential energy

¹/₂fx = mgh


h = (Fx)/(2mg) \\\\h = (58 \ * \ 0.08)/(2 \ * \ 0.02 \ * \ 9.8) \\\\h = 11.84 \ m

Therefore, the maximum height reached by the marble is 11.84 m.
