A 4.9 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 29 m above the marble's position on the compressed spring.

Question

(a) What is the change in the gravitational potential energy of the marble-Earth system during the 29 m ascent?
1 J
(b) What is the change in the elastic potential energy of the spring during its launch of the marble?
2 J
(c) What is the spring constant of the spring?
3 N/m
