Aglass falls off the counter and breaks. what is a reasonable sequence of energy transformations?
a. heat energy into kinetic energy into sound energy
b. heat energy into potential energy into sound energy
c. kinetic energy into potential energy into sound energy
d. potential energy into kinetic energy into sound energy

a and b sometimes have a positive value

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
