You have a light spring which obeys Hooke's law. This spring stretches 3.04 cm vertically when a 2.90 kg object is suspended from it. Determine the following. (a) the force constant of the spring (in N/m) N/m (b) the distance (in cm) the spring stretches if you replace the 2.90 kg object with a 1.45 kg object cm (c) the amount of work (in J) an external agent must do to stretch the spring 8.10 cm from its unstretched position J
We know that the work (W) done by a force vector F applied to an object over a displacement ?x is given byW = F(cos?) ?x,where F is the magnitude of the force, and ? is the angle between the applied force and the direction of the displacement. This expression assumes that the force is constant over the displacement ?x. If F is not constant, it can be shown that the work done is equal to the area under the curve force versus position.Based on what above said, calculate the work done by the force versus position represented in each graph (a), (b), and (c) in the figure below.
The spring-flex exercise system consists of a spring with one end fixed and a handle on the other end. The idea is that you exercise your muscles by stretching the spring from its natural length, which is 38 cm.

Problem 2: A certain spring has a spring constant k₁ = 660 N/m as the spring is stretched from x = 0 to x1 = 35 cm. The spring constant then changes to k₂ = 250 N/m as the spring is stretched to x2= 65 cm. From x₂= 65 cm to x3 = 89 cm the spring force is constant at F3 = 105 N.

Hooke’s law states that when a spring is stretched, it pulls back with a force proportional to the amount of the stretch. The constant of proportionality is a characteristic of the spring known as the spring constant. Thus a spring with spring constant k exerts a force f(x2)= kx when it is stretched a distance x. A certain spring has spring constant k =20 lb/ft. Find the work done when the spring is pulled so that the amount by which it is stretched increases from x =0 to x = 2 ft.
