1. a 2 kg body is attatched to a spring of negligible mass and oscillates with a period of 1.00 s. The force constant of the spring is?
2. The force constant of a massless spring is 25 N/m. A mass of .45 kg is oscillating in simple harmonic motion at the end of the spring with an amplitude of .32 m. The maximum speed of the mass is?
