What is the Maximum Acceleration?
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
