Your doctor has told you to watch your weight. Of course, your weight comprises two factors, so you assume that she wants you to watch both your mass and the local value of g. Which explains why you are carrying a small mass mm on an elastic band wherever you go. Most of the time, the elastic band is stretched by a distance of 2.1 cm. However, when you have finished lunch, you go into a very tall building and take the high speed lift (or elevator depending on where you live). Soon after the doors close, you notice that the band (which has linear elastic properties) is stretched by a total distance of 3.5 cm. a) At what rate is the lift accelerating? _____ m.s−2

An inclined plane of angle = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure P6.61. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?
A suspicious physics student watches a stunt performed at an ice show. In the stunt, a performer shoots an arrow into a bale of hay (Fig. P11.24). Another performer rides on the bale of hay like a cowboy. After the arrow enters the bale, the balearrow system slides roughly 5 m along the ice. Estimate the initial speed of the arrow. Is there a trick to this stunt? FIGURE P11.24
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?
When a 300-g mass is hung from the end of a vertical spring, the spring’s length is 40 cm. With 500 g hanging from it, its length is 50 cm. What is the spring constant of the spring?
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 248-g object was hung from it, the tendon stretched 1.22 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 140 N. By how much can the tendon stretch without rupturing, and how much energy is stored in it at that point? Draw free-body diagram.
An 8.0-cm-long spring is attached to the ceiling. When a 2.3 kg mass is hung from it, the spring stretches to a length of 16 cm. How long is the spring when a 3.0 kg mass is suspended from it? y=
A gymnast of mass 52.0 kg is jumping on a trampoline. She jumps so that her feet reach maximum height of 2.49 m above the trampoline and, when she lands, her feet stretch the trampoline 68.0 cm down. How far does the trampoline stretch when she stands on it at rest? Assume that the trampoline is described by Hooke's law when it is stretched. Give your answer in cm.
The figure shows two springs (k1 = 10 N/m and k2 = 20 N/m ) attached to a block that can slide on a frictionless surface. In the block's equilibrium position, the left spring is compressed by x1 = 3.0 cm .(Figure 1) a) By how much is the right spring compressed? Express your answer in centimeters. b)What is the net force on the block if it is moved 14 cm to the right of its equilibrium position?
A 65 kg student is standing atop a spring in an elevator that is accelerating upward at 2.8 m/s2. The spring constant is 2600 N/m. By how much is the spring compressed? Δy=
A very light and flexible rope is 40 cm long and is at one end attached to the ceiling. When we hang a 100 gram weight on its other end, the rope is extended by 6.0 cm. The weight is then pulled vertically down so that the ropes length is 80 cm, and then we let go of it. How fast does the weight fly into the ceiling?
A block of mass 4.9 kg is sitting on a frictionless ramp with a spring at the bottom that has a spring constant of 410 N/m (refer to the figure). The angle of the ramp with respect to the horizontal is 19° 1. The block, starting from rest, slides down the ramp a distance 32 cm before hitting the spring. How far, in centimeters, is the spring compressed as the block comes to momentary rest? 2. After the block comes to rest, the spring pushes the block back up the ramp. How fast, in meters per second, is the block moving right after it comes off the spring? 3. What is the change of the gravitational potential energy, in joules, between the original position of the block at the top of the ramp and the position of the block when the spring is fully compressed?
A bungee cord is rated at 545N/m. The jump is off a bridge above a river. Unstretched, the bungee cord is 68.0 m long. A 72.0 kg person jumps. They fall till and the cord begins to stretch. Find the amount by which cord has stretched when the person’s speed is 14.0 m/s.
