3. The figure below is the position versus time graph of a particle in simple harmonic motion. a) [1] What are the amplitude and period of oscillation of the particle? b) [3] Calculate the phase constant for this motion. c) [2] Write an equation for the particle that describes its position \( \mathrm{x}(\mathrm{t}) \) as a function of time. d) [4] Calculate the velocity and acceleration of the particle at \( \mathrm{t}=2.0 \mathrm{~s} \). 4. A 1.50 kg mass is attached to a spring with a spring constant \( 33.0 \mathrm{~N} / \mathrm{m} \) on a frictionless, horizontal
