A block of mass 2.80 kg is placed against a horizontal spring of constant k = 745 N/m and pushed so the spring compresses by 0.0550 m. HINT (a) What is the elastic potential energy of the block-spring system (in J)? When a spring is compressed or stretched, the spring potential energy, PEs = 1 2 kx2, is always positive. Gravitational potential energy, PEg = mgy, can be positive or negative depending on whether an object is above or below the y = 0 reference height. J (b) If the block is now released and the surface is frictionless, calculate the block's speed (in m/s) after leaving the spring. m/s
You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 12-m-high hill, then descends 15 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.1 m and that a loaded car will have a maximum mass of 400 kg.

The fair is in town and one of the attractions is a bungee jump. They are trying to determine the safety restrictions to prevent an accident. The length of the cord is 6.3m. The maximum distance of the fall is H=31 m, and the spring constant is K=145N/m. Given this information, what is the largest mass of jumper this attraction can allow?

A 250 gram block is dropped from rest at a height of 1.2m onto a relaxed vertical spring that has a spring constant of k =2.5 N/cm. The block continues downward, compressing the spring until it reaches its lowest point. At the lowest point, how much has the spring been compressed? Please answer in units of meters.
A block of mass 0.259 kg is placed on top of a light, vertical spring of force constant 4 800 N/m and pushed downward so that the spring is compressed by 0.108 m. After the block is released from rest, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise? (Round your answer to two decimal places.)
A 150 g particle at x = 0 is moving at 2.00 m/s in the +x-direction. As it moves, it experiences a force given by Fx =(0.350N)sin(x/2.00m). What is the particle's speed when it reaches x = 3.14 m? Note:- Consider "/" as a division symbol.
A pretty box from taylor swift batumbakal with a mass of 20.0 Kg is moving at a speed of u = 8 m/s. The smooth platform on the top has h = 50 cm from the ground. On the other hand, the rough platform at the bottom and the box has a coefficient of kinetic friction = 0.325. Also, in the bottom platform, the pretty box was able to move by R = 11.0 m before the spring, whose a spring constant k = 390 N/m, is compressed and the box stopping 1. When the pretty box reaches the bottom platform, what is its speed? 2. When it touches the spring, what is its speed? 3. How much has the spring been compressed, when the box stopped?
A glider that is 180 kg is pushed by a spring with constant 3.2*10^5 N/m down a water slide track from a height of 35m in a zig zag path. Once the slide reaches the floor level track, it will be eventually stop due to friction. Friction only exists on the ground level, and the coefficient of kinetic friction here is 0.8. If 70 meters is the max distance that the glider move on this ground level track, what is the safest maximum distance that the spring can be compressed if a 20 kg person is also on the glider.
In the Back to the Future movies, a DeLorean car of mass 1,230 kg travels at 88 miles per hour to venture back to the future. (a) What is the kinetic energy (in kJ) of the DeLorean? kJ (b) What spring constant (in N/m) would be needed to stop this DeLorean in a distance of 0.82 m? N/m
