PLEASE HELP. I truly just want to understand how to do this problem. A 1.20 kg mass on a horizontal spring oscillates on a frictionless surface with a displacement as a function of time given by x(t) = 0.075cos(4.16t – 2.45). (Units are standard units.) a.) Find the time for one complete vibration. b.) Find the force constant of the spring. c.) Find the maximum force on the mass. d.) Find the maximum speed of the mass. e.) Find the position, speed and acceleration of the mass at t = 1.00 s. f.) Find the total energy of the oscillating spring.

First off, for all trig functions of the form $$A \sin(Bx+C)$$ the period T is $$T={2\pi \over \left| B \right|}$$so that's part a)...

still with me?
what do you get for that?

Yea, I'm with you - for that part I got 2π/4.16 = 1.51 s
