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?
3.0 m s−13.0\text{ m s}^{-1}3.0 m s−1
19 m s−119\text{ m s}^{-1}19 m s−1
38 m s−138\text{ m s}^{-1}38 m s−1
180 m s−1180\text{ m s}^{-1}180 m s−1
