Only answer (e). please explain part (e) with detailed steps. Thank you
1. A 1.75-kg particle moves as function of time as follows: x=4cos(1.33t+qU/5) where distance is measured in metres and time in seconds. (a) What is the amplitude, frequency, angular frequency, and period of this motion? (b) What is the equation of the velocity of this particle? (c) What is the equation of the acceleration of this particle? (d) What is the spring constant? (e) At what next time t > 0, will the object be: i at equilibrium and moving to the right, i at equilibrium and moving to the left, iii. at maximum amplitude, and iv. at minimum amplitude.
