As a part of an exercise routine to strengthen their pectoral muscles a person stretches a spring which has a spring constant k = 740 N/m. show answer No Attempt 50% Part (a) Calculate the work in joules required to stretch the springs from their relaxed state to the position x1 = 54 cm.

= 108J

Explanation:

To develop the problem it is necessary to apply the concepts related to Hooke's Law. For which it is understood that

Where,

k = Spring constant

x = Displacement of Spring

By the theorem of work we understand that it is the force realized when there is the path of an object therefore

Our value of F is

Integrating

Therefore the expresion is

≅ 108J

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
