23. a pogo stick has a spring with a force constant of 2.50×104n/m , which can be compressed 12.0 cm. to what maximum height can a child jump on the stick using only the energy in the spring, if the child and stick have a total mass of 40.0 kg? explicitly show how you follow the steps in the problem-solving strategies for energy.

The maximum height the child can jump on the stick

h=0.459m

Explanation:

Energy conservation

Energy kinetic = Work

The energy the child do get the height jump is proportional at the distance and the consta can be compressed so:

your answer is c! hope this : )

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
