El resorte en una máquina de Pinball tiene una constante de resorte (constante de resorte = k) de 120 [N/m]. La masa del pinball es 0.010 [kg]. La bola sale del émbolo con una
velocidad de 0.3 (m/s). Suponga que la energía se conserva totalmente, calcule la
compresión, x, del resorte.

Given:
KE = 4 • my
Formula:

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
