Question
answer. c.) When the mass has fallen 3 cm from its highest point, what is the velocity of the spring?" use formula for Kinetic energy in a vertical spring system
A spring, with a spring constant of 150 N m-1, is hung vertically from a ceiling. A 5 kg mass is attached to the base of the spring and the spring is allowed to oscillate freely. For this question, ignore the effects of air resistance and friction and assume that the spring’s mass is negligible.
