A sphere of mass 7 kg is dropped fro rest from a height oh 2.8 m above the top of a spring of spring constant 1180 N/m mounted vertically on the floor . What will be the maximum compression in the spring?
The block is released from rest from the position in the picture and slides 6 meters down the frictionless incline. It strikes a spring that is at its natural length. Assume the spring is ideal and the mass of the spring is negligible. Mass of block = 20kg Incline is 30 degrees above horizontal spring constant = 200 N/m What is the max speed of the block? How far has the spring compressed when it reaches this max speed?

Elevators have many safety features. In the extremely unlikely event that the multiple steel cables supporting the elevator carriage break and the emergency brakes fail to stop it, there is an oil filled piston at the bottom of the elevator shaft to cushion the landing. Model this piston as an ideal spring and assume that the 5,500 kg carriage is initially descending at 10 m/s when it contacts the spring (initially in equilibrium). The spring brings the carriage to rest over 2 m. Use conservation of energy to determine the spring constant. Assume the friction in the system is 4000 N. You need to consider the change in gravitational potential energy for this question.
= 2. Refer to the diagram below. A spring-loaded launcher is aimed vertically upward, and compressed 0.13 m beyond its equilibrium position, then locked into place. The spring constant is k 60000 N/m. A block of mass 2 kg is placed on the launcher. When the spring lock is released, the block is launched upward to a maximum height, H. What is this height, H, if the block loses 17 Joules of mechanical energy to air resistance (during its upward flight)? Show all calculations. пиши before launch H = ? риши after launch
