Explanation:
The motion of the boat is up and down in simple harmonic with amplitude of 20 cm . Time period of oscillation T = 3.5 s and top extreme point is at level with the boarding dock .
The traveller has to wait until the boat reaches middle point ( 1o cm . ) that is half its equilibrium position of oscillation .
Time period is 3.5 s . During its oscillation from extreme top position to its half of the equilibrium position , that is 10 cm below the stationary dock , time taken by boat
t = T / 12 = 3.5 /12 = .3 s .
Man shall have to wait for a period of 0.3 s
Ans 0. 3 s .
