(a)A spring is attached to a ceiling, and has a relaxed length of 25 cm. When a mass m = 0.80 kg is attached to the spring it stretches to an equilibrium length of L0 = 34 cm.
(b) I lift the mass until the spring returns to its relaxed length, and then release it. When the mass returns to the equilibrium length, what is its speed?
(c) After I release the mass and it falls, what is the length of the spring when the mass reaches its lowest point?
The Attempt at a Solution
so K=87.2 for part A
Sorry for the missleading title but i realized im not sure how to do part b or c, i believe for part b i have to set mgy+.5mv^2=mgy+.5mv^2 but im not entirely sure
Want to make sure im doing this right before my quiz tommorow, thanks.
