Block A (with mass of 300 kg) is connected to a spring with undeformed length of 4 m and spring constant of k = 700 N/m. A strong worker then uses a rope to pull the block 3 m to the right such that the spring is stretched to a length of /= 7 m. The worker stops at this position, such that the block is at rest at this particular instant. The worker then accidentally lets go of the rope, causing the block to begin moving to the left.

You attach a block to the bottom end of a spring hanging vertically. You slowly let the block move down and find that it hangs at rest with the spring stretched by 15.0 cm. Next, you lift the block back up to the initial position and release it from rest with the spring unstretched. What maximum distance does it move down? (a) 7.5 cm (b) 15.0 cm (c) 30.0 cm (d) 60.0 cm (e) The distance cannot be determined without knowing the mass and spring constant.
Fish are hung on a spring scale to determine their mass. (a) What is the force constant of the spring in such a scale if it the spring stretches 8.00 cm for a 10.0 kg load? (b) What is the mass of a fish that stretches the spring 5.50 cm? (c) How far apart are the half-kilogram marks on the scale?
A student working on a school project modeled a trampoline as a spring obeying Hookes law and measured the spring constant of a certain trampoline as 4617 N/m. If a child of mass 27.0 kg compresses the trampoline vertically by a maximum of 0.25 m, while bouncing up and down, what is the childs acceleration at the moment of maximum compression?
The position of a particle attached to a vertical spring is given by y=(y0cost)j. The y axis points upward, y0 = 14.5 cm. and = 18.85 rad/s. Find the position of the particle at a. t = 0 and b. t = 9.0 s. Give your answers in centimeters.
You are asked to design spring bumpers for the walls of a parking garage. A freely rolling 1200 kg car moving at 0.65 m/s is to compress the spring no more than 0.090 m before stopping. What should be the force constant of the spring? Assume that the spring has negligible mass.
A mass on a spring rests on a horizontal frictionless surface. You displace it 8.00 cm 2) from equilibrium and release it from rest. Where does it reach its maximum speed? If the maximum speed is 1.25 m/s, where is the mass when it is moving at 0.75 m/s?
After driving a portion of the route, the taptap is fully loaded with a total of 26 people including the driver, with an average mass of 70 kgkg per person. In addition, there are three 15-kgkg goats, five 3-kgkg chickens, and a total of 25 kgkg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed? The spring constant is 3.3*10^4
A 50 g ice cube can slide without friction up and down a 30º slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 13.0 cm. The spring constant is 25 N/m. When the ice cube is released, what distance (in cm) will it travel up the slope above the release point before reversing direction? Use g = 10 N/kg. In your calculations, make sure you convert to consistent units (kg and meters).
A child’s toy consists of plastic attached to a spring. The spring is compressed against the floor at a distance of 2.69 cm, and the toy is released. The acceleration of gravity is 9.8 m/s2. If the toy has a mass of 115 g and rises to a maximum height of 64.5 cm, estimate the force constant of the spring in N/m.
A 3.00 ✕ 105 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.300 m by a large spring bumper at the end of its track. What is the force constant k of the spring (in N/m)?
A block of mass ?=3.80 kg slides along a horizontal table with velocity ?0=1.50 m/s. At ?=0, it hits a spring with spring constant ?=41.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.
