QUESTION:
A 5.0 g marble is fired vertically upward using a spring gun. The spring must be compressed 8.0 cm if the marble is to just reach a target 20 m above the marbles position on the compressed spring. (a) What is the change "Ug in the gravitational potential energy of the marbleEarth system during the 20 m ascent? (b) What is the change "Us in the elastic potential energy of the spring during its launch of the marble? (c) What is the spring constant of the spring?
ANSWER:Step 1 of 3 a) The change in the gravitational potential energy of the marble is given by, Given, Mass of the marble, The initial position of the marble, The final position of the marble, So, The change in the gravitational potential energy of the marble is .
