Describe a model that could represent the total energy of a system as a relationship between the motion of particles on both the microscopic and macroscopic level?

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

i think the answer is a, hope this : )

b. a lightning bug, plug of grass, and a worm
