Chapter 7, Problem 42P
The nuchal ligament is a cord-like structure that runs along the back of the neck and supports much of the head’s weight in animals like horses and cows. The ligament is extremely stiff for small stretches, but loosens as it stretches further, thus functioning as a biological shock absorber. Figure 7.17 shows the force-distance curve for a particular nuchal ligament; the curve can be modeled approximately by the expression F(x) = 0.43x − 0.033x2 + 0.00086x3, with F in kN and x in cm. Find the energy stored in the ligament when it’s been stretched (a) 7.5 cm and (b) 15 cm.

A center hurls a basketball m = 1 kg straight up with an initial speed of v0 = 7.5 m/s. He releases the ball at shoulder height h0 = 1.7 m. Let gravitational potential energy be zero at ground level.
Give the total mechanical energy of the ball E in terms of maxium height hm it reaches, the mass m, and the gravitional acceleration g.
What is the maxium height hm in meters?
A sledgehammer of mass m = 1.9 kg falls freely vertically downward from a height of h = 2.5 m at an initial speed of v = 6.5 m/s before striking a partially buried piling. After the blow the piling has moved d = 0.075 m deeper. How much force, in newtons, was applied to the piling? Assume all the energy goes towards driving the piling into the ground, and the force of the sledgehammer is constant over the distance d that the piling is driven into the ground. Note that you can ignore the change in potential energy of the piling itself. Further, because d is so small compared to h, you can also ignore the change in potential energy of the hammer as well as it moves distance d.

The ad says that the minimum weight of a jumper is 120 lb and the maximum weight is 250 lb. It also says that the pogo stick uses a patented system of elastometric rubber springs that provides up to 1200 lbs of thrust, something common helical spring sticks simply cannot achieve (rubber has 10 times the energy storing capability of steel). a.

Comment on the claim that rubber has 10 times the energy-storing capability of steel. c.

The surface on which the ball moves is inclined = 10.0 with respect to the horizontal. The spring is initially compressed its maximum distance d = 5.00 cm.
