As shown in the figure below, a spring having an initial unstretched length of fo is stretched by a force F applied at its end. The stretched length is . By Hooke's law, the force is linearly related to the spring extension by F = k(Co) where k is the stiffness. Unstretched spring FL (l-(₂) If stiffness is constant, evaluate the work done, in J, if lo = 3cm, 1 = 6cm, l2 = 15 cm, and the stiffness is k = 2 x 104 N/m.

A bungee cord is essentially a very long rubber band that can stretch up to four times its unstretched length. However, its spring constant vanes over its stretch [see Menz, P.G. “The Physics of Bungee Jumping.” The Physics Teacher (November 1993) 31: 483-487]. Take the length of the cord to be along the direction and define the stretch as the length of the cord minus its un-stretched length that is, (see below). Suppose a particular bungee cord has a spring constant, for of and for.

A pendulum, comprising a light string of length L and a small sphere, swings in the vertical plane. The string hits a peg located a distance d below the point of suspension (Fig. P7.80). (a) Show that if the sphere is released from a height below that of the peg, it will return to this height after the string strikes the peg. (b) Show that if the pendulum is released from rest at the horizontal position ( = 90) and is to swing in a complete circle centered on the peg, the minimum value of d must be 3L/5. Figure P7.80
Parcels of air (small volumes of air) in a stable atmosphere (where the temperature increases with height) can oscillate up and down, due to the restoring force provided by the buoyancy of the air parcel. The frequency of the oscillations are a measure of the stability of the atmosphere. Assuming that the acceleration of an air parcel can be modeled as 2zt2=g(z)0zz , prove that z=z0etN2 is a solution, where N is known as the Brunt-Väisälä frequency. Note that in a stable atmosphere, the density decreases with height and parcel oscillates up and down.
Hanging from the ceiling over a baby bed, well out of baby’s reach, is a string with plastic shapes, as shown here. The string is taut (there is no slack), as shown by the straight segments. Each plastic shape has the same mass m , and they are equally spaced by a distance d , as shown. The angles labeled describe the angle formed by the end of the string and the ceiling at each end. The center length of sting is horizontal. The remaining two segments each form an angle with the horizontal, labeled . Let T1 be the tension in the leftmost section of the string, T2 , be the tension in the section adjacent to it, and T3 be the tension in the horizontal segment.

Prof. P. built a wooden pendulum clock over the break between Winter and Spring quarters during the COVID lockdown (he really did!) If the length of the pendulum is 30.56 cm and the pendulum is pulled to the right 4.8 cm from the equilibrium position to start it moving and it starts at rest, what is the greatest speed of the pendulum as it swings? (Assume that the pendulum swings freely with no friction and use energy considerations to solve)
