A boat is sent across a river with a velocityof 8 kmfh. Ifboat is 10 km/h, the river is flowing with avelocity of36.the resultant velocity of the |
|
Answer» The boat’s velocity and the river velocity will give the boat a new resultant velocity. As the boat’s velocity is perpendicular to river velocity, Assume that, VB= Velocity of boat VR= Velocity of river Apply pythagoras theoram, Resultant velocity2= VB2+VR2 102=82+VR2 100 = 64 +VR2 VR2 = 36 VR = 6 km/h hit like if you find it useful |
