4. A 490 g dynamics cart is held at rest next to a Hooke's Law spring that is compressed by 44.0 cm. The spring has a force constant of 150 N/m. The cart is released and travels along a horizontal surface; the surface is smooth except for a 1.0 m rough patch where a 4.0 N force of friction acts. The cart then travels along a frictionless incline. What is the maximum height (h) reached by the cart, above the horizontal surface? 1.0 m ➜ rough patch

A block is placed on top of a vertical spring, and the spring compresses. Figure P8.24 depicts a moment in time when the spring is compressed by an amount h. a. To calculate the change in the gravitational and elastic potential energies, what must be included in the system? b. Find an expression for the change in the systems potential energy in terms of the parameters shown in Figure P8.24. c. If m = 0.865 kg and k = 125 N/m, find the change in the systems potential energy when the blocks displacement is h = 0.0650 m, relative to its initial position. FIGURE P8.24

4. You decide to take the plunge and go bungee jumping. Being a college student, you do this on the cheap, and buy a bungee cord with a spring constant of k = 500 N/m and a length of L = 8.0 m. You choose a bridge where you tie the end of the cord so you can jump off. Assume that you step off the bridge with zero speed and for safety assume a mass of 100 kg. a. How high must the bridge be so that you can do this fun jump more than once? (Being nervous, you want to be extra safe. What should you assume for air resistance?) b. What is the magnitude and direction of the maximum spring force during your jump?
Tendons. Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke’s law. In laboratory tests on a particular tendon, it was found that, when a 250 g object was hung from it, the tendon stretched 1.23 cm. (a) Find the force constant of this tendon in N/m. (b) Because of its thickness, the maximum tension this tendon can support without rupturing is 138 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point?

3. A 320 g block is released from rest on a 37º ramp and slides down the ramp a distance d until it contacts a spring of spring constant 820 N/m. The coefficient of kinetic friction between the block and the ramp is 0.26. It compresses the spring 5.3 cm before coming to a stop. How much was the distance d it travelled down the ramp before contacting the spring?

Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 4.90 x 105 N/m, the helper spring constant is 3.60 x 105 N/m, and yo = 0.500 m. Truck body Axle (a) What is the compression of the leaf spring for a load of 4.70 x 105 N? 0.87 Your response differs from the correct answer by more than 10%. Double check your calculations. m (b) How much work is done in compressing the springs? 0.855 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J
You attach a 2.10 kg weight to a horizontal spring that is fixed at one end. You pull the weight until the spring is stretched by 0.300 m and release it from rest. Assume the weight slides on a horizontal surface with negligible friction. The weight reaches a speed of zero again 0.100 s after release (for the first time after release).
