(The cheese and the spring are not attached.) Use 9.81m/s4 for the acceleration due to gravity use 9.81m/sfor the acceleration due to gravity Express your answer using two significant figures IIm Submit Give Up Continue >
Explanation / Answer
let the height the cheese rise is h
using conervation of energy
spring potential energy = potetnial energy of cheese
0.5 * k * x^2 = m*g*h
0.5 * 2100 * 0.132^2 = 1.09 * 9.8 *h
h = 1.83 m
cheese rises to 1.83 m height
