The piston in the cylinder head of a locomotive has a stroke (twice the amplitude) of 1.0m. If the piston moves with simple harmonic motion with an angular frequency of `200rev//`min., what is its maximum speed ?

Explanation

`a = (1)/(2)m = 0.5m`
`omega = 200` rev/min
`v_(max) = aomega = (1)/(2) xx 200 = 100` m/min
