On a pleasure cruise a boat is traveling relative to the water at a speed of 5.0 m/sec due south. Relative to the boat, a passenger walks. Toward the back of the boat at a speed of 1.5 m/sec.

(a) What is the magnitude and direction of the passenger’s velocity relative to the water?
(b) How long does it take for the passenger to walk a distance of 27 m on the boat?
(c) How long does it take

Respuesta :

Answer:

Explanation:

Given

Velocity of boat w.r.t water [tex]v_{bw}=5 m/s[/tex]

Velocity of Person w.r.t boat [tex]=-1.5 m/s[/tex] as walk towards the back

[tex]v_{bw}=v_b-v_w[/tex]

[tex]v_{pb}=v_{p}-v_{b}[/tex]

thus [tex]v_{p}=5-1.5=3.5 m/s[/tex]

(b)Time taken by Passenger to walk 27 m on the boat

[tex]t=\frac{27}{3.5}=7.71 s[/tex]
