You place the spring vertically with one end on the floor. You then lay a 1.60-kgkg book on top of the spring and release the book from rest. Find the maximum distance the spring will be compressed.

3.92 cm

Explanation:

Assuming spring cinstant of 800 N/m, we know that the potential energy is transformed to kinetic energy in spring hence

where m is the mass of the block, g is acceleration due to gravity, x is the extent of compression of the spring and k is spring constant. Making x the subject of the above formula then

Substituting 1.6 kg for m, 9.81 for g and 800 N/m for k then

i was thinking more like reflects green light, just not sure

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
