The elastic energy stored in your tendons can contribute up to 35% of your energy needs when running. Sports scientists find that (on average) the knee extensor tendons in sprinters stretch 45 mm while those of nonathletes stretch only 32 mm. The spring constant of the tendon is the same for both groups, 33 N/mm. What is the difference in maximum stored energy between the sprinters and the nonathletes?

How far, in meters, would a spring, with a spring constant of 184.8 N/m, need to be stretched in order to have an elastic potential energy of 47.7 Joules?
A spring with a constant of 19.5 N/m is stretched from its equilibrium position by 27.6 cm. How much elastic potential energy is stored in the spring?
Your answer is partially correct. Try again. In the figure, a spring with spring constant k = 180 N/m is at the top of a frictionless incline of angle e = 38°. The lower end of the incline is distance D = 0.92 m from the end of the spring, which is at its relaxed length. A 1.5 kg canister is pushed against the spring until the spring is compressed 0.22 m and released from rest. (a) What is the speed of the canister at the instant the spring returns to its relaxed length.(which is when the canister loses contact with the spring)? (b) What is the speed of the canister when it reaches the lower end of the incline?

The Slingshot is a ride for two people. It consists of a single passenger cage, two towers, and two elastic bands. Potential energy is stored in the elastic bands and the passenger cage is released. On the way up, this potential energy in the elastic bands is converted into the kinetic energy of the cage. At the maximum height of the ride, the energy has been converted into gravitational potential energy of the cage. The slingshot has two towers of height h = 71 m. The towers are a distance d = 31 m apart. Each elastic band has an unstretched length of L0 = 42 m and a spring constant of k = 295 N/m. The total mass of the passengers and cage is m = 395 kg. The car is pulled down to the ground in the middle of the two towers.
A spring is connected on one end to a wall and the other is free to be compressed. The spring constant is 25 N/cm for the spring. A 2.0 kg mass is pressed against the spring and then released and the entire system is placed on horizontal frictionless surface. (a) How much is the spring compressed when 15.0 J of energy is stored in the spring? (10.9 cm) (b) What is the acceleration when the spring is at 1/2 the maximum compression distance? (68.5 m/s2) (c) What is the maximum speed of the mass?
The magnitude of the force required to compress an imperfect horizontal spring a distance x is given by Fbs = kx +bx^3 where k=120N/m and b=18N/m^3. If you use a 7.5kg block to compress the spring a distance of 1.6m and then let it go, what speed will the block have when it leaves the spring? Assume the surfaces are smooth enough that any frictional forces can be neglected.

A swift blow with the hand can break a pine board. As the hand hits the board, the kinetic energy of the hand is transformed into elastic potential energy of the bending board; if the board bends far enough, it breaks. Applying a force to the center of a particular pine board deflects the center of the board by a distance that increases in proportion to the force.Ultimately the board breaks at an applied force of 800 N and a deflection of 1.2 cm.a. To break the board with a blow from the hand, how fast must the hand be moving? Use 0.50 kg for the mass of the hand.b. If the hand is moving this fast and comes to rest in a distance of 1.2 cm, what is the average force on the hand?

Suppose a stretched spring is used to supply power to a light bulb. The spring has a spring constant k=34.0 N/m and is stretched from its equilibrium length (which is the length where the spring force is zero) by a length 2.24 m. If the spring returns to its equilibrium length in 55.3 seconds, what is the average power in Watts that could be transferred from the spring to the light bulb?
A small 0.40-kg box is launched from rest by a horizontal spring as shown in the figure below. The block slides on a track down a hill and comes to rest at a distance d from the base of the hill. The coefficient of kinetic friction between the box and the track is 0.30 along the entire track. The spring has a spring constant of 34.0 N/m and is compressed 30.0 cm with the box attached. The block remains on the track at all times. 30.0 cm This answer has not been graded yet. (b) Calculate d. m 50.0 cm (a) What would you include in the system? Explain your choice. 40° -d = ?
