1. The problem statement, all variables and given/known data
A 0.85kg mass oscillating on a spring w/ spring constant of 45 N/m. How do i determine angular frequency?
A 0.85kg mass oscillating on a spring w/ spring constant of 45 N/m. This object reaches a maximum position of 12 cm from equilibrium. Determine:
a.) angular frequency of this mass
b.) force
c.) acceleration
d.) elastic potentional energy
e.) kinetic energy
Determine:
f.) velocity that it experiences at its maximum position.
Determine:
g.) force
h.) acceleration
i.) potential elastic energy
j.) kinetic energy
k.) velocity that it experiences at the equilibrium position.

2. Relevant equations

3. The attempt at a solution
okay so i got parts a through e, but for g through j... didnt i already answer those in b through e?

Hi livblue23,

I could be wrong (having the word Determine appear right before f is a bit confusing), but do they mean to evaluate b-f at the maximum position, and g-k at the equilibrium position?
