Chap. 11, #16. (II) A 0.60-kg mass vibrates according to the equation where x is in meters and t is in seconds. Determine (a) the amplitude, (b) the frequency, (c) the total energy, and (d) the kinetic energy and potential energies when x = 0.30 m.

To find the answers to the given questions, we need to analyze the given equation. However, you mentioned that there is an equation missing. It is important to provide the complete equation in order for me to guide you accurately. Can you please provide the missing equation?

wouldn't it be logical to take the equation.

amplitude is the x one way.
frequency is 1/t

yes it will be logical
