Ablock slides with no friction and hits a spring with spring constant k=2000 n/m. the block compresses the spring in a straight line for a distance 0.15m. the block’s kinetic energy, in j, at that point is 0 j. what was its initial kinetic energy, in joules?

To solve this exercise it is necessary to apply the concepts related to kinetic energy in a spring.

By definition the kinetic energy keeping what is stipulated in the stable Hooke law that

Where,

K = Spring constant

x = Displacement

Our values are given as,

x = 0.15m

k = 2000N/m

Therefore replacing

Therefore the initial kinetic energy is 22.5J

no

sodium is solid at rt

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
