rest. Find the speed with which the object passes through its original position on the way up.

An object with a mass of 7.13 kg is attached to the lower end of an ideal spring and lowered gently.if the spring constant of the spring is 509N/m, then how far, in meters, did the lower end of the spring move as the object was being lowered
In a car's suspension system, each wheel is connected to a vertical spring; these springs absorb shocks when the car travels on bumpy roads. In one car, each spring has a spring constant of 4.6×104N/m.If this 1500 kg car is driven at 27 m/s through the bottom of a circular dip in the road that has a radius of 625 m, by how much do these springs compress compared to when the car is driven on a flat road?

A spring 1.50 m long with force constant 442 N/m is hung from the ceiling of an elevator, and a block of mass 13.3 kg is attached to the bottom of the spring. (a) By how much is the spring stretched when the block is slowly lowered to its equilibrium point? (Enter the magnitude only.) m(b) If the elevator subsequently accelerates upward at 1.56 m/s2, what is the position of the block, taking the equilibrium position found in part (a) as y = 0 and upwards as the positive y-direction. (Indicate the direction with the sign of your answer.) ?m(c) If the elevator cable snaps during the acceleration, describe the subsequent motion of the block relative to the freely falling elevator. What is the amplitude of its motion? ?m
a 2 kg weight is fasten to a spring on an inclined plane. It has a spring constant of 20 N/m. When the spring is relaxed, the mass sits at the bottom of the incline. It is compressed 0.25 m from its relaxed position, and the weight is released. It goes down the incline, to the horizontal surface and up a second, identical incline. If there were kinetic friction between the weight and the right incline, but none between the weight and the left incline, what would be the coefficient of kinetic friction μk so the maximum height reachable is the same as the starting position (i.e. d=0.25m).
