A passenger railroad car has a total of 8 wheels. Springs on each wheel compress—slightly—when the car is loaded. Ratings for the car give the stiffness per wheel (the spring constant, treating the entire spring assembly as a single spring) as 2.8 x 107 N/m. When 30 passengers, each with average mass 80 kg, board the car, how much does the car move down on its spring suspension? Assume that each wheel supports 1/8 the weight of the car.

An ornament of mass 46.5 g is attached to a vertical ideal spring with a force constant of 22.4 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch? Give answer in cm
An ideal spring hangs vertically. When a 453 g object is hung from the bottom end, and lowered gently, the spring stretches 5.58 cm. How much would be the spring have stretched, in cm, if the mass of the object had been 560 g instead? x'=?
An ornament of mass 40.6 g is attached to a vertical ideal spring with a force constant (spring constant) of 45.6 N/m. The ornament is then lowered very slowly until the spring stops stretching. How much does the spring stretch?
A 5 kg box rests on a tabletop. On one side, it compresses a spring with a stiffness of 1000 N/m by 1 cm. If the friction force cancels out the force of the spring what must be the minimum coefficient of static friction between the box and table to keep the box from moving?
To measure the static friction coefficient between a 1.6-kg block and a vertical wall. A spring (spring constant = 510 N/m) is attached to a block. Someone pushes on the end of he spring in a direction perpendicular to the wall until the block does not slip downward. If the spring in such a setup is compressed by 0.039 m, what is the coefficient of static friction?
One end of a light spring with spring constant k₁ is attached to the ceiling. A second light spring is attached to the lower end, with spring constant k₂. An object of mass m is attached to the lower end of the second spring. (a) By how much does the pair of springs stretch? (Use the following as necessary: k₁, k₂, m, and g, the gravitational acceleration.) Xtotal = X Because the springs are light, you can treat them as essentially massless, so the only downward force acting on them is mg. Use |F| = kx to find the amount of stretch, x, for each spring, and then find the sum. (b) What is the effective spring constant of the spring system? (Use the following as necessary: K₁, K₂, m, and g, the gravitational acceleration.) Keff X Use your result from part (a), and recast it into the form |F| = Keff* total Solve for keff. = (c) What If? Two identical light springs with spring constant k3 are now individually hung vertically from the ceiling and attached at each end of a symmetric object,…
I attach a metal block to a vertical spring and it stretches by 6 cm. If I replace the block with another one twice the mass, the spring will stretch another 3 cm, making the total stretch 9 cm. another 6 cm, making the total stretch 12 cm. another 12 cm, making the total stretch 18 cm. more than another 12 cm.
