A 50-g mass vibrates in SHM at the end of a spring. The amplitude of the motion is 12 cm, and the period is 1.70 s. Find: 

(a) The frequency, 

(b) The spring constant, 

(c) The maximum speed of the mass, 

(d) The maximum acceleration of the mass, 

(e) The speed when the displacement is 6.0 cm and the mass is moving to the right, and 

(f) The acceleration when x = 6.0 cm and the mass is moving to the right.
