Chapter 7, Problem 7.66P
A basket of negligible weight hangs from a vertical spring scale of force constant 1500 N/m. (a) If you suddenly put a 3.0-kg adobe brick in the basket, find the maximum distance that the spring will stretch, (b) If instead, you release the brick from 1.0 m above the basket, by how much will the spring stretch at its maximum elongation?

A spring, with a spring constant of 750 N/m, is hung vertically from the ceiling. If a mass of 500 kg is added to this spring, how much will it elongate?
A vertical spring has a force constant of 150 N/m. By how much will the spring
be compressed if a mass 1.30 kg is placed on top of it?
An unstretched spring is 15.00cm long. When you hang a 795g weight from it, it stretches to a length of 17.00cm.
B.)What total mass must you hang from the spring to stretch it to a total length of 20.00cm?

From slow-motion video, the speed of his 1.50-kg hand descending on a block was estimated to be 15.0 m/s, which decreased to a speed of 0.500 m/s in the 2.50 103 s during which his hand made contact with and broke through the block. The maximum shear stress a concrete block can be subjected to before breaking is 9.50 105 N/m2. a. What was the force exerted by Lees hand on the block? b.
