Some passengers on an ocean cruise may suffer from motion sickness as the ship rocks back and forth on the waves. At one position on the ship, passengers experience a vertical motion of amplitude 1.4 m with a period of 17 s.
What is the maximum acceleration of the passengers during this motion?
= (2p / T )2 A
= ( 2 x 3.14 /13 ) 2 ( 1.2 m )
= 0.28 m/s2
What fraction is this of g?
= (0.28 / 9 .8)
= 0.02 g
