The position of a particle is given by the expression x = 4.00 cos (6.00πt + π), where x is in meters and t is in seconds.

(a) Determine the frequency. Incorrect: Your answer is incorrect. How is the frequency related to the angular frequency? Hz

(b) Determine period of the motion. Incorrect: Your answer is incorrect. How is the period related to the frequency? s

(c) Determine the amplitude of the motion. Incorrect: Your answer is incorrect. The amplitude is always a positive number. m

(d) Determine the phase constant. Incorrect: Your answer is incorrect. What is the phase constant in the equation x(t) = cos(ωt + ϕ)? rad

(e) Determine the position of the particle at t = 0.270 s.
