A person lying on an air mattress in the ocean rises and falls through one complete cycle every five seconds. The crests of the wave causing the motion are 21.3 m apart. Determine (a) the frequency and (b) the speed of the wave.
(a): __________ Hz
(b): __________ m/s
(a): __________ Hz
(b): __________ m/s
-
a) Frequency = (1/5) = 0.2Hz.
b) Velocity = (21.3 x 0.2), = 4.26m/sec.
b) Velocity = (21.3 x 0.2), = 4.26m/sec.
