Set the controls as follows.

• x₀= -8cm
• k=60N/m
• m=4kg

Now hit start and observe the motion of the block and the plots on the graphs for position, velocity, and acceleration.

Which of the following statements accurately describes your observation? (Select all that apply.)

The maximum displacement was8cm.

The maximum displacement was 0 cm.

The speed of the block remained constant.

The acceleration of the block remained constant.

The frequency of the block remained constant.

The period of the block remained constant.

• Part II

Set the controls as follows.

• x₀= 8cm
• k=60N/m
• m=1kg

Now hit start and observe the motion of the block and the plots on the graph for position, velocity, and acceleration.

• Part III

Set the controls as follows.

• x₀= 6 cm
• k=30N/m
• m=5kg

If you wanted to adjust the settings but keep the period the same as in the above what would you do? (Hint: Think about the dependency of period on the initial displacement, spring constant, and mass. Select all that apply.)
