8. The diagram shows a 2 kg block attached to a Hookean spring on a frictionless surface. The block experiences no net force when it is at position B. When the block is to the left of point B the spring pushes it to the right. When the block is to the right of point B, the 410.tem- spring pulls it to the left. The mass is pulled to the right from point B to point C and released at time t = 0. The block then oscillates between positions A and C. Assume that the system consists of the block and the spring and that no dissipative forces act. a) The block takes 40.0 s to make 20 oscillations. What is the "period of oscillation" for this system? b) What is the frequency of this oscillating system? c) What is the amplitude of vibration of this system? d) Determine the spring constant of the spring. f) Explain what would happen to the period and frequency of this system if you were to double the amplitude while keeping the mass and spring constant the same. g) Explain what would happen to the period and frequency of this system if you were to double the mass while keeping the amplitude and spring constant the same. h) Explain what would happen to the period and frequency of this system if you were to double the spring constant while keeping the amplitude and mass constant
