A piston in a high-performance engine undergoes simple harmonic motion with a stroke (the total distance between its highest and lowest points) of 80 mm. The engine runs at a constant speed of 4500 revolutions per minute4500\text{ revolutions per minute}4500 revolutions per minute.
What is the maximum speed of the piston?
