workout the problem. What is the Volume of a spring if its Density is .03 Hectograms/cm3 and its mass is 9 grams?
The diameter of a car's suspension spring decreases uniformly. The force exerted by the spring is given by F = axb. Consider a suspension spring that compresses x1 = 12.4 cm with a 1,000 N load and x2 = 34.0 cm with a 5,000 N load. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) (a) Find the constants a (in units of N/mb) and b. a= b= (b) Calculate the work (in J) needed to compress the spring 24.0 cm. (Assume the spring is not initially compressed.) J
A spring suspended from a ceiling has a constant of 12 Ib/ft. An 8 Ib weight is placed on the spring, and when equilibrium is reached, the weight is raised 5 in. above the equilibrium position and dropped. Solve for the displacement (x) of the weight at any time (t). Type or paste an image of your solutions below:
An object is placed on the end of a vertical spring, with a spring constant of 484.1 N/m. The spring is stretched by 0.09 m. Calculate the mass of object.
You construct a dart gun using a spring that has a spring constant of 250 N/m. The dart you wish to launch has a mass of 0.3 kg, and compression length of the spring you design to be 0.4m. If you load and fire this dart from the dart gun, how fast will the dart's launch velocity be? Give your answer in units of m/s, however do not include the units explicitly in your answer. If you include units, the answer will be counted wrong.
A block attached to a vertical spring oscillates up and down, the length of a spring is shown below. The mass of the block is 5.0 kg. What is the spring constant of the spring, in N/m? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive.
