A harmonic oscillator is described by the function x(t) = (0.500 m) cos(0.470t). Find the oscillator's maximum velocity and maximum acceleration. Find the oscillator's position, velocity, and acceleration when t = 2.25 s. HINT (a) oscillator's maximum velocity (in m/s) 4.00.235 m/s (b) oscillator's maximum acceleration (m/s) 4.00.110 m/s (c) oscillator's position (in m) when t = 2.25 s 4.0 x m (d) oscillator's velocity (in m/s) when t = 2.25 s 40 X m/s (e) oscillator's acceleration (in m/s) when t = 2.25 s 4.0 m/s
