38.Apersonaiming to reach the exactly opposite point on the bank of a stream iswimmingwith a speed of 0.5m/s at an angleof 120° with the direction of flow of waterThe speed of water in the stream is |

Answer» Vᵣ = velocity of river or stream = ? Vs = velocity of swimmer = 0.5 m/s V= resultant velocity given angle is total angle ie 90+30= 120 From figure in triangle Δ sin θ = p/ h sin 30⁰ = Vᵣ / Vs 1/2 = Vr/ 0.5 so Vr= 1/4 ie Vr = 0.25 m/s so velocity of river is 0.25 m/ s hit like if you find it useful |
