Solve the given parts of following problem:
Problem: When a 420 gram mass is attached to a spring, it oscillates with a period of 0.350 s. If instead, a different mass m2 is attached to the same spring, it oscillates with a period of 0.700 s.
Part A: Find the force constant of the spring?
Part B: Find the mass m2?
I need help to determine the force constant of the spring.
