(a) Find the amplitude, frequency, and period of motion for an object vibrating at the end of a horizontal spring if the equation for its position as a function of time is the following. x = (0.300 m) cos ~ t ) A= m f = Hz T = (b) Find the maximum magnitude of the velocity and acceleration. max m/s a max m/ s 2 (c) What are the position, velocity, and acceleration of the object after 1.40 s has elapsed? x = m m/s a = m/s2 EXERCISE HINTS: GETTING STARTED | I'M STUCK! If the object-spring system is described by x = (0.300 m) cos (1.45t), find the following. (a) the amplitude, the angular frequency, the frequency, and the period A = m 0 = rad/s f = Hz T = s (b) the maximum magnitudes of the velocity and the acceleration max m/s a max = m / s 2 (c) the position, velocity, and acceleration when t = 0.250 s x = m V = m/s m / s 2 Need Help?
